Hi @Paul Norrod 

Welcome to the community.

As your tags on the post display that this is relating a DC instance, look at the log files on the server Jira is running on.

If oyu can't contact your Jira admin or the local IT department to help out.

Hi and welcome to the Community @Paul Norrod 

The "400 Bad Request Request Header Or Cookie Too Large" message from nginx is the key detail here. It usually means that either Jira or the reverse proxy sitting in front of it is hitting a limit on the size of the headers or cookies your browser is sending. Since GitHub is a perfectly valid host for the plugin, the problem is likely with the request size rather than your Git configuration.

I’d suggest testing this in an incognito window first to see if that clears it up. If it works, you’re probably dealing with "cookie bloat" from your SSO or a browser extension that's stuffing too much data into your headers. If it still fails, your Jira admin will likely need to adjust the "maxHttpHeaderSize"  in the Tomcat or Nginx settings. It looks like Jigit is just passing along a low-level infrastructure error, so focusing on those server limits is your best bet.
