Certificate expired or not yet valid

Products

• CA API Gateway

Issue/Introduction

We are seeing that requests to a backend host via the 'Route Via Http(s)' assertion fails with the following:

Problem routing to https://xxxxx:443/xxxxx Error msg: Unable to obtain HTTP response from https://xxxxx:443/xxxxx: Certificate expired or not yet valid: CN=xxxx.com

Environment

CA API Gateway

Cause

There is an issue with the certificate being presented to the gateway from the backend host.

Executing the following on the gateway showed that the certificate was indeed expired:

openssl s_client -connect BackendHostName:443

Resolution

Get the certificate updated on the backend host such that it is no longer expired.
