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.

@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.

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.
