So, here's the situation. The certificate we used on our jira/confluence machines has expired, so we got ourselfs a new one and i simply exchanged the old certificate with the new one. The root CA remained the same as well as the intermediate CA. The used certificate is a wildcard. So basically the same certificate is installed and trusted on both machines. However, when trying to link the two over application links, both machines tell me that the certificate used on the other machine can't be trusted since it's not installed locally.
Both machines are running behind a nginx reverse proxy and according to tomcat's documentation there is no need for a .jks in that case.
Now my question is, am I missing something?
Thanks for your replies.
