Actually this is not the first time this happens on customers on Contabo. If it happens, does asystemctl restart docker help?

if its about the Cloudron app package itself, then probably athttps://git.cloudron.io/cloudron/collabora-app/issues

Unfortunately, I don't think there is some automated way to do this, yet. However you can install the nextcloud app on your Cloudron and selectLeave user management to the app during installation, then you somehow have to export and import the database backup. You can get a remote shell connection into the Cloudron app via the dashboard andhttps://cloudron.io/documentation/apps/nextcloud/#running-occ-tool mentions how to run occ correctly. Regarding importing the files with potentially setup share/access permissions, I am not sure myself how to do this correctly. Maybe there are upstream migration guides which handle that case?

@malvim the payment already went through. Thanks for letting us know about the situation.

We published a few monica app updates yesterday, can you update the app to the latest and check if the issue persists?

From what I can tell from the upstream documentation, the widget is mostly an unstyled link for now, pointing to a mailtrain rendered form for subscribing. You would have to style it yourself for now. As it is still marked as experimental, it will probably get enhanced at some point.

Oh indeed, currently Cloudron only supports Ubuntu 16.04 as being an LTS release for now. Sorry that it wasn't clear upfront.

The HASH_SALT does look a bit concerning, have to look into this.
The APP_KEY is now generated on first startup and thus unique to your installation. If you want to recreate it, you have to runphp artisan db:seed --class ActivityTypesTableSeeder --force from within a terminal into the app (You can get this through the Cloudron dashbaord) However I don't think this is required, given that it is unique to your instance already.

@makemrproper that won't be possible, as all apps have to be packaged for Cloudron and generally installing other services on the side is not supported. However often unsupported apps can be hosted with the lamp app itself or you can also build custom packages for unsupported apps. Seehttps://cloudron.io/developer/packaging/

I just gave it a try and yes, you should put the adjusted snippet into /app/data/production.toml inside the mailtrain app and then restart the app (there is a restart button in the terminal view in the Cloudron dashboard for the app)
