environment : python 3.7.4 cas-server : django-mama-cas cas-client : django-cas-ng

I use above package to build cas service. It somtime will show 500 Internal Server Error and below log. After a few moment, it will work normally. I don't know why QQ Can anyone can give me some direction or hint to debug with this problem.

[2020-03-16 03:30:45,811] ERROR   | log.py 228 @ log.log_response => Internal Server Error: /cas/logout

@manelclos @jbittel Could you encounter the similar problem? Is any ideal or comment about this error? Should I provide other log or setting? Thanks for reply.

manelclos commented 3 years ago

Hi @max533, sorry for the late reply. It doesn't look like a problem related to django-mama-cas, but network or setup related. It seems that when trying to log out the user, the connection is not accepted in the other end.
