JIRA/Confluence issue "Received the following HTTP error code from the server:504"

[Moi Mah]

Hi everyone,

I'm running an on premise JIRA Confluence solution that are used for documentation, Change and more.

Don't laugh at me cause I'm inheriting this infrastructure.

I'm running a Confluence version 6.15.4 and a JIRA version Jira v8.4.1

Since my beloved CISO asked me to switch it from HTTP to HTTPS, I'm having this message even if I tried to change on macros to get ride of this message.

Current addresses and they run on the same server/IP:

https://Confluence.intranet.local:8444/

https://jira.intranet.local:8443/

My company doesn't want to invest and move to the Cloud version and asks me to fix this issue.

The only fix that doesn't suits the CISO, is a rollback to the HTTP.

I tried to find the thread that can help me, but didn't find any. That's why I've decided to ask any help from a Superman who can you help me fixing this issue?

Really appreciate if so.

Thanks

Moi
