Nextcloud AiO custom SSL certificate


I got a perfectly working Nextcloud AiO setup, currently updated to 24.0.1.

Now I have to move it out from the internet-connected DC into the internal network, not connected to the world. Everything was fine until Let’s Encrypt cert expired.

Now I have to manually replace this expired cert with the newly generated one. Self-signed, commercial, or dns-verified Let’s Encrypt.

So, here is my question: how can I insert a custom cert into the AiO?

You cannot. However see this: Initial Setup requires External domain address · Discussion #1155 · nextcloud/all-in-one · GitHub
