Can you hit ctrl+shift+I in Firefox (open development console), select
'Network' tab there, hit reload, and explore the requests/responses
there when the error is manifested. Unfortunately, there is no way to
copy out the whole traffic but you can at least make screenshots.

This approach allows you to see what's happening inside the
communication without need to decode SSL traffic in Wireshark.
