HTTP Status 500 – Internal Server Error. How can I deal with this error? #12

Closed sot232 closed 5 years ago

sot232 commented 5 years ago

For some reasons, I started to receive this error message about 20 or 30 minutes ago.

Right now, if I access BYU CAS on an incognito mode, I have no problem with CAS. But I can't access CAS without an incognito mode. I tried to clear browser cache, wait for a bit and try logging in again, and tried to log in on a sub url. However, nothing has been worked.

My guess is that I have to wait for an hour or so to resolve this issue. But after my web app launches, users shouldn't experience the same issue and wait for a long time to resolve it. How can I deal with the Internal Server Error in the future?

Yeah, CAS had some issues today. In such a situation, there's absolutely nothing that can be done in a browser plugin like this. Or a server-based plugin for that matter. If the "Central Authentication System" is broken, then by definition Authentication isn't working.

I am sorry if my question wasn't clear.

I know I can't do a whole lot when CAS is broken. But I was able to access CAS on incognito mode even though I couldn't access the same thing on a normal browser. To me, it seems like somewhere on your side stores my broken call and blocks accessing CAS even if CAS is properly working.

Is there anything I can do for this particular situation?

snelg commented 5 years ago

I can see how it would seem like that. Yes, saved session/cookies were involved in the whole mess today, but they were browser cookies on the CAS site itself. So still nothing this code library could handle in any way.
