Our player only show the logo

I would take a look at this similar thread:

If you look at your logs, it says “Activity threshold exceeded. There are 1 processes” for 3F-L, 11F-L, and 10F-L. The user claims to have fixed it by deleting the Xibo Library folder and forcing a check-in from the player.

Additionally, ensure that your CMS is actually listening on HTTPS, since you are forcing it, and also make sure that XMR is working correctly for proper server/client communications. I don’t even see an XMR address specified in your settings file. I also don’t see a valid email address, so if these are actually Android players, you’ll need to buy the perpetual license.
