My containers disapeared. Need to recover Nextcloud AIO Login

Summary of the issue you are facing:

I don’t know what happened, but I woke up the other day and AL of my NC containers were gone. The volumes are still intact. So, used my startup script to re-install NC. Now, I need to log into the AIO page to start the other containers.

However, even though I wrote down the backup key, that key doesn’t work. So, how can I determine what the correct key is, or change it to something that I know?

TIA,

Mike.

Initial startup of Nextcloud All-in-One complete!

You should be able to open the Nextcloud AIO Interface now on port 8080 of this server!

E.g. https://internal.ip.of.this.server:8080

:warning: Important: do always use an ip-address if you access this port and not a domain as HSTS might block access to it later!

If your server has port 80 and 8443 open and you point a domain to your server, you can get a valid certificate automatically by opening the Nextcloud AIO Interface via:

https://your-domain-that-points-to-this-server.tld:8443

Hi, can you follow GitHub - nextcloud/all-in-one: 📦 The official Nextcloud installation method. Provides easy deployment and maintenance with most features included in this one Nextcloud instance. · GitHub and start at point 11?

I stopped, removed, and restarted the AIO container. When I point my browser at 192.168.1.15:8080, as indicated, I get the AIO login screen. However, the backup key that I noted in the original installation doesn’t work.

I will need to recover the AIO login credentials.

How can I do this?

Mike.

Maybe this helps? How to re-obtain/retreive the Nextcloud AIO passphrase? · nextcloud/all-in-one · Discussion #1786 · GitHub

That was the ticket! I was able to recover the password, log into AIO, and run the update. Of course, the update also started each container. So, I am back up and running!

Thanks again,

Mike.
