could not create etherpad author / could not create etherpad group

[dannywelz]

Hello,

we recently upgraded to moodle 4.1.1+ and are using the Pluginverison v4.0-r7 (2022-12-15) 2022083104 and a fresh pulled etherpad/etherpad Docker Image.

The Problem:
When i create a new etherpad activity, on saving the activity Moodle throws: could not create etherpad group
When i open an old etherpad activity, on saving the activity Moodle throws: could not create etherpad author

Here are the facts:

• Docker Image without any changes to the settings

• Etherpad up and running on another server reachable from our moodle on port 80, which is configured within the moodle plugin settings.

• Etherpad is reachable and usable directly on that configured domain.

• For the moment there is no SSL.

• We had the "could not get api version" or something error, which happened due to a missing "/" at the end of the etherpadlite | url. Since this is gone now, i think the connection works basically.

Do you have an Idea whats causing our Problems?

Best Regards
Danny
