Hey folks!
I've installed Grav 1.3.10 on a Nginx/PHP 7.0 Linux server, all requirements are met, the CLI GPM works fine. I've run through https://learn.getgrav.org/troubleshooting/common-problems#cannot-connect-to-the-gpm which told me now was the time to come here! (I'm not seeing anything terribly recent in the discussions here on this either.)
Trying to figure out why in the Admin interface I am seeing "The connection to the GPM cannot be established."
Is there something else I should check not in the troubleshooting info?
Is there any specific info that is needed to diagnose why this is happening?
