Can't reach my Nextcloud after restore

Nextcloud AIO v12.5.0

Hi.

I want to move my Nextcloud AIO from my Synology with Synology reverse proxy to a Debian 13 server without a reverse proxy.

The Backup with AIO’s internal borg backup on Synology works perfectly. Restoring to the Debian 13 server also works.

All containers are started and are ok.

But when I want to open my nextcloud page only “page loading error” is in the Browser.

If I do a new installation without a restored backup with the same docker compose file, the nextcloud works.

Here the AIO Log:

please can somebody help me.

This seems to be the problem

3

Ok. Thanks

So it seems that after restoring the backup, Docker is using a network that doesn’t exist?

Is there a way to change that?

Because, as I said, a fresh installation works.

4

For now you can work around it by creating the frontend_net docker network manually

5

We have a bugfix for this now in only allow to set `APACHE_ADDITIONAL_NETWORK` via environmental variable and do not restore it on backup restore by szaimen · Pull Request #7520 · nextcloud/all-in-one · GitHub

6

This is now released with v12.6.0 Beta. Testing and feedback is welcome! See GitHub - nextcloud/all-in-one: 📦 The official Nextcloud installation method. Provides easy deployment and maintenance with most features included in this one Nextcloud instance.

7

Okay, great.

Is it sufficient ithat the instance used for restoration is set to beta, or also the instance from which the backup is made is set to beta?

8

They are intercompatible

9

Do I just need to uncomment “APACHE_ADDITIONAL_NETWORK: frontend_net” in my compose.yml file?

10

Yes, this is definitely a good idea if the docker network does not exist on the target server.

11

So I set both instances to the beta version and added “APACHE_ADDITIONAL_NETWORK: frontend_net” to the recovery server in the compose.yaml. But the problem still exists.

This is also strange in the AIO log of the Synology is the same entry but connection works there.

You need to remove this setting on your synology. Otherwise it will not work as the network apparently does not exist there. Alternstively, create the docker network frontend_net on your synology manually.

APACHE_ADDITIONAL_NETWORK: frontend_net

Is not in the Synology (Backup) only in the new Debian 13 ( Recovery) compose.

14

I see. Did you already change the synology install of AIO to the new beta release?

15

Yes, both instances have migrated to Beta V12.6.0. But still no connection to the recovered nextcloud on the debian system without reverse proxy.

Here both compose files:

So if you open the AIO interface, you see version v12.6.0?

Also, can you please post the output of sudo docker inspect nextcloud-aio-mastercontainer from the synology instance here?

18

Thanks! And if you open the AIO interface now, do you see version v12.6.0?

19

Yes

Cool! So the containers seem to all up and running which is good, so the initial error seems to be gone

I think we have a misunderstanding. I want to switch from a Synology NAS to a Debian server, and Nextcloud isn’t working on it after restoring it.
