Quick reference for the most common issues. If nothing here helps, contact support@tigertrust.io — include your workspace ID (from Settings → Workspace) and a timestamp.

​
Agent won’t connect

Symptom: Integrations → Agent Setup shows the agent stuck in disconnected, or a newly-installed agent never appears in the inventory.
1

Check the agent logs on the host

journalctl -u tigertrust-agent -f          # systemd
docker logs tigertrust-agent               # container
Look for dial tcp:, EOF, certificate verify failed, or 401 Unauthorized.
2

Confirm outbound reachability

The agent talks to our Collector over HTTPS. From the host:
curl -v https://collector.tigertrust.io/healthz
Expected 200 OK. If TLS or DNS fails, your egress firewall or DNS resolver is blocking the connection.
3

Verify the enrollment token

Tokens are single-workspace, revocable at any time. If someone rotated it after install:
  • Integrations → Agent Setup → Regenerate token
  • Reinstall (or edit /etc/tigertrust/agent/config.yaml) with the new token
  • systemctl restart tigertrust-agent
4

Check the audit log

Monitoring → Audit Logs, filter by action = agent.enroll.failed. The reason column tells you exactly why: expired token, wrong workspace, invalid signature.

​
Certificate issuance fails

  • Verify the target hostname resolves publicly (dig +short <host>).
  • Confirm port 80 is open from the internet to the responding agent — HTTP-01 requires plain HTTP briefly.
  • Check the ACME challenge log under Certificates → Issue → Recent Attempts. Timeout waiting for challenge = firewall; unauthorized = wrong file served.
  • Under Integrations → DNS Providers, click Test on the provider. It should return “credentials valid”.
  • Confirm the API credentials have write permission for the zone you’re issuing for.
  • For providers with slow propagation (some managed DNS): increase the propagation-wait under Advanced settings.
  • Authorities → CA Management → your CA → Health shows the last error. 401 = expired API credentials. 403 = domain not on your account’s whitelist.
  • Contact your CA’s account manager to confirm the domain is authorised on your contract.
Check the policy on the template you used (Certificates → Templates). Common causes:
  • Key size below policy minimum (bump the CSR key size)
  • Subject CN/SAN doesn’t match template regex
  • Requested validity exceeds template max

​
Discovery scan finds nothing

Symptom: cloud discovery scan completes successfully but no certificates appear.
1

Verify IAM permissions

Each cloud provider has a minimum required IAM policy — see AWS, Azure, GCP. Cross-check the policy attached to the credentials you added.
2

Check regions

Scans default to the regions in your provider config. Certificates in other regions won’t be discovered until you add them.
3

Look for filter mismatches

Discovery → Discovered Certificates hides items that already match a live cert. Toggle Show already-imported to see everything.

​
Webhooks not firing

1

Check delivery attempts

Integrations → Webhooks → your endpoint → Deliveries. Each attempt shows the response code and body from your server.
2

Common failure codes

  • 401/403: your server rejected our request. Verify your signature-verification logic. See Webhooks.
  • 5xx: your server errored. Fix the endpoint; we retry with exponential backoff.
  • timeout: your endpoint took >10 seconds. Move heavy work to a background queue and 200 immediately.
3

Endpoint auto-disabled?

After 10 consecutive failures we disable an endpoint to protect your infrastructure. Fix the issue, then hit Re-enable on the endpoint page.

​
SSO login fails

IdP metadata drifted. Settings → SSO → your provider → Refresh metadata.
The user’s email domain isn’t mapped to a workspace. Add a mapping under Settings → SSO → Domain mappings, or invite the user manually first.
The IdP isn’t sending the group claim we expect. Check the Group attribute setting under Settings → SSO → your provider. Common defaults: groups, memberOf, roles.

​
TPM attestation denied

Symptom: the attest-and-provision call returns 403 attestation_failed. The response failures[] array tells you exactly which check tripped. Common codes:
FailureMeaningFix
quote_verify: nonce mismatchAgent used a stale or wrong nonceAgent should fetch a fresh nonce per attestation
pcr_mismatch:<n>PCR value differs from policy expectationDevice boot state changed. Verify with tpm2_pcrread and update the policy if legitimate
pcr_missing:<n>Policy requires this PCR but agent didn’t quote itAdd the PCR to the agent’s pcr_selection config
certify_verify: bound public key modulus does not matchCSR key doesn’t match TPM2_CertifyAgent bug — regenerate CSR from the same TPM-resident key
ek_chain: ...EK certificate doesn’t chain to a trusted rootContact support to add your TPM vendor’s root to our trust store
nonce_expiredAgent took >5 minutes between challenge and evidenceReduce agent-side latency; the default TTL is 300 seconds
secure_boot_not_measuredPCR7 is zero — Secure Boot is offEnable Secure Boot in device firmware, then re-attest
See TPM policies for how to relax or tighten policy safely.

​
Collecting a support bundle

When escalating, include:
  1. Your workspace ID (Settings → Workspace → General).
  2. Timestamps in UTC with a ±5-minute window.
  3. The relevant audit-log entries (Monitoring → Audit Logs → Export CSV).
  4. For agent issues: last 500 lines of agent logs (journalctl -u tigertrust-agent -n 500 > agent.log).
  5. For webhook issues: the delivery attempt IDs from the Deliveries tab.
Email the bundle to support@tigertrust.io with a description of what you expected vs. what happened.
