Enabling Jira for HTTPS with self signed certificate

[Roger Spraggon]

I followed the instructions in https://confluence.atlassian.com/adminjiraserver085/running-jira-applications-over-ssl-or-https-981155619.html (for self signed certificate) however when I try to access Jira after enabling either "HTTP and HTTPS" or "HTTPS only" I get "https://xxxxxxx.domain.local:8443/secure/errors.jsp" and "Jira access problem" with a blank screen. I'm also still getting a certificate error, not sure if this should go away if changes have been done correctly or if there is something that I've missed 

I have tried to modify the home URL page to match the https and port 8443 before restarting the Atlassian service but this doesn't make any difference.

I've looked at the log files and I'm not seeing anything that stands out though I'm not 100% sure which log file to look at and what to look for.

Hi! 

I'd recommend you try to make call using

curl -vvv https://xxxxxxx.domain.local:8443

As a result you can see what exactly broken in certificate.

This is the result from curl:

curl -vvv https://xxxxx.domain.local:8443
* Trying ::1:8443...
* Connected to xxxxx.domain.local (::1) port 8443 (#0)

curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and
