Unstick the agent waiting on a DNS TXT record it misconfigured

TL;DR

The agent wrote the wrong TXT value or the wrong host, so verification will never pass no matter how long it waits. Verify the record independently with a DNS lookup, delete the wrong record, write the exact host and value the provider shows, then re-check.

The problem

provider asks for: host "_verify", value "abc123xyz"
agent created: host "verify", value "abc123" (truncated)
agent status: waiting for DNS propagation... (6 hours and counting)

Fix it

Step 1: Look up what actually exists in DNS

Query the record yourself with a DNS tool, for both the host the agent claims it created and the host the provider asked for.

Expected: you see the real TXT value in DNS, and you can compare it character by character with the provider's expected value.

Step 2: Delete the wrong record

Remove the misconfigured record from the DNS zone before writing the correct one. Leaving both creates ambiguity about which one the verifier reads.

Expected: a fresh lookup returns no TXT record at the wrong host.

Step 3: Write the exact host and value from the provider console

Copy the host and value directly from the provider's verification page - do not let the agent retype, truncate, or "clean up" the value. Quoted strings stay quoted exactly as shown.

Expected: the new lookup returns the exact value the provider expects.

Step 4: Wait for TTL, then trigger verification

Wait out the record's TTL, confirm the lookup is stable from two different resolvers, then click verify in the provider console.

Expected: verification passes on the first attempt after the correct record propagates.

Step 5: Put a verification gate in the agent's flow

After the agent writes any DNS record, the next step must be an independent lookup that compares the live value to the expected value, and the run must stop if they differ.

Expected: a misconfigured record fails fast with a diff instead of stalling for hours.

When this applies

• Domain verification stalls for hours with a TXT record the agent created
• The record in DNS does not match the provider's expected host or value
• The agent keeps polling instead of checking its own work

When it doesn't

• The record is correct and just propagating (check TTL and be patient)
• The provider's verification endpoint is down (verify from their status page)
• The failure is an SSL or CAA issue rather than TXT verification

Compatibility

SendGrid, Google Workspace, Microsoft 365, and any SaaS domain verification flow; Cloudflare, Route53, and other DNS providers for the record side.

Variant phrasings

domain verification stuck after agent added txt record

Same fix. "Stuck" almost always means "wrong" when an agent wrote the record.

agent keeps waiting for dns propagation that never completes

Propagation of a wrong value completes just fine - the verifier still rejects it. Compare values, not clocks.

Why it happens

Agents copy verification values through several steps - reading the console, storing in memory, writing to the DNS API - and each hop can truncate, reformat, or drop characters. Underscore-prefixed hosts get "normalized" away, long values get cut. The agent then polls for propagation of a record that is already fully propagated and simply wrong, and the loop has no step that compares the live value to the expected one.

Edge cases

• Multiple TXT records at the same host: some providers read only the first; delete extras
• DNS provider API caching: the write may succeed but read back stale for a minute
• Apex vs subdomain: the agent may have written the record at the wrong level of the zone

If it still fails

• Capture the expected host and value, the live lookup output, and the provider's exact error before changing anything else.
• Reproduce with a single test record so you are not debugging a crowd.
• Check the DNS provider and SaaS status pages; outages look exactly like config errors.

Prevention

• Agents never write DNS records without an immediate independent read-back and diff.
• Store verification values verbatim; never let the agent retype them.
• Cap DNS wait loops with a hard timeout and a value-diff check before giving up.

Fix agent loop polling a DNS record that never propagates

TL;DR

The agent polls forever because nothing distinguishes a slow record from a wrong one. Check the authoritative nameserver once; if the record is wrong there, fix it instead of polling. Poll with a deadline, and on expiry report the diagnosis, not just a timeout.

The error

Agent loop detected
Polling DNS record that never propagates after DNS check timeout.

Use this skill

Agent? Search Vectle for this error:

curl -s "https://vectle.com/api/v1/search?q=agent loop detected polling dns record that never propagates after dns check timeout"

Fix it

Step 1: Check authoritative once

Query the authoritative nameserver for the record.

Expected: If wrong there, the record is misconfigured. Fix it and stop polling.

Step 2: Set a poll deadline

Bound the polling loop with a deadline tied to the TTL.

Expected: Polling ends with a verdict instead of looping forever.

Step 3: Back off between polls

Space polls increasingly.

Expected: Less noise and cleaner logs.

Step 4: Report the diagnosis on expiry

On deadline, report the record, nameserver, and observed values.

Expected: Humans get the facts instead of a bare timeout.

Step 5: Fix the record and re-run

Correct the DNS record if needed and run the check again.

Expected: The check passes within the deadline.

When this applies

• Agents poll DNS records that never appear
• DNS checks loop past their timeouts
• You are building DNS-waiting agents

When it doesn't

• The record is correct and visible (extend the deadline)
• DNS delegation is broken (fix the nameservers)
• The agent polls the wrong record (check the query)

Compatibility

DNS polling in agents. Standard resolver behavior.

Variant phrasings

agent polling dns never propagates

Same loop. Authoritative check first, deadline always.

dns poll loop agent timeout

Timeouts without deadlines are infinite loops. Bound them.

agent stuck waiting dns record

Stuck usually means polling a wrong record. Verify authoritative.

Why it happens

Polling loops without a reality check cannot tell slow from wrong. A misconfigured record never propagates no matter how long you wait, so the loop is futile from the start. One authoritative query distinguishes the two cases instantly.

Edge cases

• Negative caching can hide a just-fixed record; wait out the negative TTL
• Log each poll's answer so the pattern is visible
• Separate the poll deadline from the overall run deadline so one check cannot hang the run

If it still fails

• Reproduce with a minimal run: one user, one file, one step.
• Read the agent's full trace, not just the final error; the failure is usually upstream.
• Check the underlying API or tool directly, outside the agent, to separate agent bugs from service bugs.
• Reduce concurrency to one and see if the failure persists; races hide as flakes.
• If the run is business-critical, add a human checkpoint before the destructive steps.

Prevention

• Checkpoint long runs so any failure resumes instead of restarting.
• Cap and back off every retry loop; unbounded retries are outages waiting to happen.
• Validate inputs at each pipeline stage; fail fast with clear errors.
• Log enough context per step that a timeout is diagnosable without rerunning.
• Give destructive steps a human checkpoint or a dry-run mode.

Fix DNS propagation stuck during new domain onboarding

TL;DR

Propagation that seems stuck is usually a wrong record or a cached old value, not slow DNS. Check the record with dig against the authoritative nameserver first; if it is wrong there, fix it. Only then blame caching, and lower the TTL for the next change.

The error

DNS propagation stuck
New domain records not visible after many hours. Onboarding blocked.

Use this skill

Agent? Search Vectle for this error:

curl -s "https://vectle.com/api/v1/search?q=dns propagation stuck new domain onboarding"

Fix it

Step 1: Query the authoritative nameserver directly

dig @[nameserver] [record] [type] for the record in question.

Expected: If the authoritative server shows the wrong value, the record itself is wrong. Fix it there.

Step 2: Check public resolvers

Query a couple of public resolvers and compare.

Expected: If they differ from authoritative, you are seeing cache; note the remaining TTL.

Step 3: Fix the record if wrong

Correct the value at your DNS provider.

Expected: Authoritative answers are now correct.

Step 4: Wait out the TTL or flush where you can

Wait for the old TTL to expire; flush local and OS caches in the meantime.

Expected: Resolvers converge on the new value as TTLs expire.

Step 5: Lower TTLs before the next change

Drop the TTL to a few minutes well ahead of future changes.

Expected: The next change propagates in minutes, not hours.

When this applies

• New domain DNS changes seem stuck for hours
• Onboarding is blocked waiting on DNS
• You are cutting a domain over to new infrastructure

When it doesn't

• The authoritative server is correct and resolvers agree (the problem is elsewhere)
• The domain does not resolve at all (check delegation and nameservers)
• Only one network sees the old value (that network caches aggressively)

Compatibility

DNS generally. dig and standard resolver behavior.

Variant phrasings

dns not propagating new domain

Same troubleshooting. Authoritative first, then caches.

dns changes taking too long

Too long usually means a high TTL was set before the change. Lower TTLs ahead of changes.

domain onboarding dns stuck

Onboarding checklists that wait on DNS should verify against authoritative servers, not public ones.

Why it happens

DNS has two layers: what you published (authoritative) and what resolvers remember (cache). Most stuck propagation is actually a wrong authoritative record, and the rest is resolvers honoring a long TTL you set before the change. True propagation delay beyond TTL expiry is rare.

Edge cases

• Some ISP resolvers ignore TTLs and cache longer; you cannot fix their behavior
• Negative caching means a queried-missing record stays missing for the negative TTL
• Changing nameservers themselves takes the longest; plan those moves carefully

If it still fails

• Verify from multiple networks; one network's cache is not the internet's state.
• Check the domain's delegation and nameservers before blaming individual records.
• Wait out one full TTL after a fix before declaring it still broken.
• Keep a known-good dig output to diff against during the next incident.
• If a provider's verification never passes with correct records, escalate with dig output and timestamps.

Prevention

• Lower TTLs a day before any planned DNS change.
• Verify every record with dig against authoritative before declaring done.
• Monitor certificate and domain expiry with alerts, not memory.
• Keep DNS change history; most outages are a bad edit, not propagation.
• Test verification flows in staging with a throwaway subdomain.
