What Happened?
- Your TLS certificate for the HTTP load balancer is expiring and automatic certificate renewal is failing.
Environment
- F5® Distributed Cloud (XC) Console
- HTTP Load balancer
Resolution/Answer
- If you have added new domains to the load balancer, please make sure to map the CNAME for that domain.
- If no new domains are added, please check and confirm if you have done the CNAME mapping properly.
Cause
- Missing CNAME mapping for any domain in the load balancer can cause this issue.
Additional Information
- For delegated domain XC will take care of all the things once the NS record created for the delegated domain in the root domain registrar.
- However in case of non delegated domain you need to take care of DNS records. You can use DIG command to check and confirm the CNAME mapping.
