Unable to Log In

I am trying to log in to the panel, but I click the log in button and it shows the loading circle for a second, and then nothing happens.

I have tried in different browsers, clearing site data, rebooting the server.

Anyone had this happen or have any advice?

What web server type and version are you using? Try switching to Apache and see if that helps:

appcd-cli change-webserver apache

Could the server be out of disk space? It would cause this behaviour.

The panel is on an OLS server and has 450GB+ Free space. Haven't changed any config files.

I restarted appcd from the cli and that worked. I'm not sure why but I have had services randomly stopping and not restarting lately.

MediaLabz OLS was doing this kind of behaviour once to me. But it was fixed with update or something
