Hi, thank you for reporting this!
Could you be a bit more specific. When do you get this error? Did you have a look into the settings. What is it showing? Maybe there was a change in your environment.

Best regards

Hi Andreas,

thanks for your quick answer!

The first one directly during update / at the end of the update (just updated etherpad-plugin, no other changes in parallel); the second one entering the settings.
In the meantime i rolled back to the previous, working, etherpad-version. But i remember red font in the plugins-settings saying "our Moodle server may not be able to connect to the Etherpad server. Please check your configuration!"

There was NO change in our environment. Using v4.2-r5 everything works fine, so also after rollback to that version setting "2023072700" in the DB for mod_etherpadlite in mdl_config_plugins table.

Best regards and nice weekend!

Hello,
we got the same issue with updating Etherpad. We updated to Moodle 4.1.6 and the Etherpad.
There were no changes made in the configuration.

This is the error: The Moodle server could not get the api version! Your Moodle server may not be able to connect to the Etherpad server. Please check your configuration!

Greetings,
Malte

Update:
We changed the Etherpad URL in the configuration. We just removed the last "/" in the end of the URL and it is working now.
Maybe its something similar for you... the URL we used for the earlier Version had the / at the end and worked..

Best regards!
Malte

Hi at all, I really can not reproduce this problem :(.
I tried with PHP 8.0 and PHP 8.1 and Moodle 4.1, 4.2 and 4.3.
I tried with and without "/" at the end of the server url.
All test were successful.
So I really don't know, what else I can do.
Maybe someone posts his plugin configuration (without the apikey of course).

Thank you!
