Dear all,

I experienced an issue with collabora. Files cannot be saved due to some issue.

I am currently running the following setup:
Nextcloud: 18.0.4
Collabora App: 3.6.0
PHP: 7.3.18

Please find the logfiles from docker below:

Can anyone help?

Is cloud.myhomepage.com your server?

Please fill out the support intro for further assistance.

Thanks for asking.

I replaced my domain-name with “myhomepage“.
But basically yes, the nextcloud instance is running on my VPS.
