504 gateway Timeout NGINX when testing SMTP
Hi,
I am entering the SMTP credentials of a couple of providers (to discard provider issues) in the gancio configuration and I get a 504 gateway timeout NGINX error every time (see screenshot).
Since I tried 2 different providers, I guess the problem is on my side. Is there any configuration that I should add on NGINX to make SMTP work?
Thanks,
