> 
> 1. tailscale running on phone 100.104.107.18
> 
> 2. tailscale running on cloudserver [boudreaucloud.tail348316.ts.net](http://boudreaucloud.tail348316.ts.net) or 100.125.208.48
> 
> 3. I’ve tried to add an entry in the config.php for 100.104.107.18 but this didnt do anything

Have you seen [How to enable-https with a tailscale cert? · Issue #2684 · nextcloud-snap/nextcloud-snap · GitHub](https://github.com/nextcloud-snap/nextcloud-snap/issues/2684), maybe that helps?

Here’s a guide for Nextcloud AIO, [Easy setup: Container-less Tailscale as reverse proxy · nextcloud/all-in-one · Discussion #6817 · GitHub](https://github.com/nextcloud/all-in-one/discussions/6817), dunno if you can make heads or tail-scales out of that 😆

Bar having used tailscale or similar personally, you’ll have to wait for knowledgeable folks to help sort out your issue, so please be patient…
