How to Resolve the "An error occurred while processing X509 certificates" Error in IBM HTTP
This error will occur when the certificate is not in the correct format. When checking that the certificate is properly formatted it is recommended that you view the file in a plain text editor such as Notepad.
A common issue with the formatting of the certificate is that it is missing the beginning and end tags. Be sure to include the beginning and end tags:
-----BEGIN CERTIFICATE-----
-----END CERTIFICATE-----
There should be no leading or trailing spaces before or after the "begin" and "end" lines.
Check your certificate installation for SSL issues and vulnerabilities.
