[BUG] Error while login on instance setup using docker-compose

[Aadesh-Baral]

/system/authentication/login throws error after the authorization on instance setup using docker. This issue is probably related to gevent as this issue started after the update of gevent and greenlet in #5316 which had to be done to resolve #5300.

Error log:

I've managed to fix this issue by using gevent.monkey.patch_ssl() before any imports on backend.__init__.py. Most of the solution on the internet points out setting gevent.monkey.patch_all() , since we have issue around the SSL i've patched SSL only instead of patching everything. But i am not sure if this is a right way of solving this issue. If anybody have faced this issue any help will be hugely appreciated.

I'm having the same issue, the workaround proposed by @Aadesh-Baral seems to work fine.

Probably fixed by #5642 . Needs to be verified.

Not relevant anymore as the login works well with recent docker setup
