Certificate Status Issues

Certificate shows “error” status

Cause: We couldn’t establish a connection to retrieve the certificate. Solutions:
  1. Verify the domain is publicly accessible (try curl -v https://yourdomain.com)
  2. Check if your firewall allows inbound HTTPS connections
  3. Ensure DNS is properly configured for the domain
  4. Verify the server is running and accepting connections on the specified port

”Connection timeout” error

Cause: The server didn’t respond within 10 seconds. Solutions:
  1. Check if the server is under heavy load
  2. Verify network connectivity to the server
  3. If your server legitimately needs more time, contact us

”DNS resolution failed”

Cause: We couldn’t resolve the hostname to an IP address. Solutions:
  1. Verify the hostname is spelled correctly
  2. Check your DNS configuration
  3. Ensure the domain’s DNS records are publicly accessible

”Connection refused”

Cause: The server actively refused our connection. Solutions:
  1. Verify the port is correct (default is 443)
  2. Ensure the service is running on that port
  3. Check firewall rules allow inbound connections

Wrong certificate detected

Cause: A CDN, load balancer, or proxy is serving a different certificate. Note: The certificate we see is exactly what your users see. If this differs from your origin certificate, check your CDN/proxy configuration.

Notification Issues

Not receiving alerts

Solutions:
  1. Go to Settings → Channels and verify the channel is enabled
  2. Click “Test” to send a test notification
  3. Check the channel’s last error message for details
  4. Verify alert routing rules include your certificates

Slack notifications not working

Cause: The webhook URL may be invalid or expired. Solutions:
  1. Go to your Slack workspace settings and create a new incoming webhook
  2. Update the webhook URL in Settings → Channels
  3. Click “Test” to verify it works

Email notifications going to spam

Solutions:
  1. Add [email protected] to your email contacts
  2. Mark our emails as “Not spam” in your email client
  3. Check your organization’s email filtering rules
