Summary of the issue you are facing:
Hi All,
I installed Nextcloud AIO on a local VM. Working great! As a beginner I’m experimenting with Nextcloud Talk. So, to be able to use/test it with a few people simultaniously, I setup an HPB server and filled in the details in the admin settings in Nextcloud. This works! The URL and secret are accepted and we can make calls. Whohoo.
But, when I wake up next morning the admin settings are being overwritten by my local username and password and the URL settings of the HPB server are all gone, causing an error. Why is it overwriting my settings and how do I stop that?
