On HTTP Load Balancers allow certificate files up to 20 kB.
When importing a TLS certificate, the upload file function restricts the file size for PEM or PKCS12-encoded certificate to 10 kB. A custom certificate we are trying to use on F5 Distributed Cloud load balancers are 14 kB with the full cert chain in the file.See comment below: avoid uploading certificates in the HTTP Load Balancer, instead use the Certificate Management feature:
Please increase the limit to allow certificate files up to 20 kB.
Summary of steps:
1. Upload the root cert
2. Upload the intermediate cert
3. Upload the custom TLS certificate
4. Edit HTTP load balancer(s) to use custom TLS certificate from Certificate Management

This idea is a poor suggestion, as it is preferred to use the built in TLS storage options in F5 XC, instead of trying to load the certificate directly in an HTTP load balancer!
