Crash on login sometimes

[DiomedesDominguez]

This morning when I was trying to login the page returned me back to the login page, like there was an issue validation the authentication.

After trying with several other social networks, I noticed in LinkedIn that the response URL was giving an 503, so I try again with google and I check the browser's console for any error message:

This is the error I got when trying to login with LinkedIn or Twitter:

I'm using Firefox 72.0.1 (64-bit) on Ubuntu 19.04 and Microsoft Edge Beta on Windows Server 2019.
