Api Error: "Invalid key supplied"

Maybe, you can test it With my CM/S? Then i can send you the keys

Your CMS is accessible on cloud ?

Yes, it is possible via cloud

OK then, we’ll continue in private message to exchange keys and I’ll come back here to give you the solution.

Hmm, maybe a feature request to gain an access token via the UI (it is possible in some other software)

Access token has a lifetime.So it won’t be possible, unless remove the time limit, but that’s a security vulnerability.

Ask your hosting provider to look at the reverse proxy logs.
This is my public IP Address:

what should i find in the logs? i find your ip in the access logs

are you using IIS, apache or Docker installation?

Apache Installation With php 8.1

Other than the access logs, we need to see if there are any errors.
