@fbartels Indeed! I changed the title accordingly.

As @msbt mentions, the proper solution is to have the preview generator fixed, not to create band-aids for that on the platform level. @necrevistonnezr maybe you can comment on that github issue to raise awareness, afterall it is basically just a missing feature of the application, not Cloudron as such.

@nebulon Could https://git.cloudron.io/cloudron/nextcloud-app/issues/61 be related?

I dont see how this can be supported by nextcloud, unless it would scan the authors inbox. Maybe the nextcloud email addon is able to handle this, but you should probably ask nextcloud support about this.

As a first attempt, you could try to restart the box process with systemctl restart box Also maybe look at the system logs, in case there are any hints for errors.

The update to 15 is pushed out now. Please report any issues you encounter if that is the case.

Currently there is no integration between Cloudron groups and groups inside an app. I agree that this is a good feature to have though.

Have pushed an update that enables this.

You were right. "unbound" was failed. Turns out IPV6 was disabled which was causing "unbound" to fail and in turn causing the issues with resolving domain names in Nextcloud. This is a vanilla install of Ubuntu 16 LTS so I'm not sure what happened. I enabled IPV6 and rebooted and everything started working. Thanks for the tip.

Thanks for the reply! Definitely a great start, we will take it from there and refine it to put in our documentation to get more people started.

Lets further handle this in the opened issue tracker item.

Also, it is safe to disable encryption since the communication is internal to the VM.

Sorry, I've finally solved the issue, if the answer can help :

@yylevas No worries! Glad you found the problem. Breaking stuff is the fastest way to learn!
