Cloudron Forum

I have been trying to install cloudron on my homeserver for a while now without luck, please help.

My homeserver is running linux and I have setup a quickemu ubuntu-server vm for running cloudron.
When I run the install/setup script it just looses internet connection. ping no longer works, dns resolve also stops working.
The issue is reproducible quite easily. I will add below the log output.
Same issue with the full ubuntu 22.04 distro in the same setup.

Thanks

Thanks for your reply @girish
unbound was active and running and the host command was not working.
I did the forward everything setup but that did not fix the issue. btw only after the forward everything change did I start to get the SERVFAIL responses to the host commmand; before that it was just the same reply as when unbound is not installed at all.

Fortunately I just tried deactivating my VPN on the host machine and it worked! The installation was able to proceed.
In my case I will need to re-activate the vpn so it might not be a complete solution

I wanted to let you know how I got everything to work, it might help other users.

The initial issue was about DNS resolution. The quick fix is indeed to use the forward-everything option in unboud but with the previously used dns server. To find that value you just need to do a resolvectl and look at the value of the Current dns servers. In my case it was 10.0.2.3 (the one that was linked to my vpn on the host machine of the server). That is enough to fix the installation script losing internet.

For the Configuration error: Domain resolves to ["XXX.XXX.XXX.XXX"] instead of IPv4 XX.XX.XX.XX the quick fix in my case (home server not directly exposed to the internet) was to install an openvpn server on the vps server (https://www.cyberciti.biz/faq/ubuntu-22-04-lts-set-up-openvpn-server-in-5-minutes/) and an openvpn client on my home server so that my home server gets the vps's IP address. In this setup you I also need a reverse proxy to expose the 80 and 443 ports from the home server to the vps.
