AIO admin page. It shows all are running fine.

my npm configuration:


Portainer log shows this:

Trying to fix docker.sock permissions internally…

Creating docker group internally with id 988

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 all-in-one/reverse-proxy.md at main · nextcloud/all-in-one · GitHub?

I tried all these. Couldn’t make it to work. FInally gave up and installed Docker version of Nextcloud. It was smooth and worked in first try itself.
