No reconnection via Ethernet if connection is lost
-
Hello,
I am currently running Cloudron on a home server on Ubuntu 22.04 with a LAN connection to my router.
I currently have the problem that when e.g. the router restarts, the connection is not properly restored because Cloudron remains unreachable. Only after restarting the server is everything accessible again. Since I am not a Linux expert, I wanted to ask if there are specific settings in Cloudron or for the network adapter in Linux to solve this problem.

I don’t have this issue on my home server and I go through many power and internet downtime. I live in a thunderstorm prone area.
Are you using a dedicated card or the built in one? What hardware are you running?

@humptydumpty Okay, interesting. Then it must be somewhere in my configuration I think. I use a built-in one. I use a Minisforum UM760 Pro as a small home server.
@ByMynix Nice unit! When I set up my home server, I remember that the default setting for the storage type (something LVM related) wasn't the same as others have mentioned. I think this was in Ubuntu server 20.04. Maybe, the image you got has some different settings pre-configured?

@humptydumpty Thank you very much! That's good to know. I'm using Ubuntu 22.04 LTS Server and have gone through the standard setup + software RAID 1. Other than that, I haven't actually changed anything on the system, beside from Stuff Like fail2ban. Maybe there are certain auto connect options that are not activated?

It's probably some linux server or VM setting. Are you running Cloudron via a Hypervisor? Ubuntu/Linux should automatically re-connect.
If you are using DHCP on the network, assign Cloudron a static IP on the router. Otherwise, ubuntu has to get a new lease and it might take it some to figure this out.

@girish Finally, I would like to say that I haven't quite figured out what the problem was. I had used Cloudron bare metal. In the last few days I switched to Windows Server and have Cloudron running in a Linux VM via Hyper V. I then assigned a manual IP there and the problem no longer occurs.
I guess it would have been fixed before with a manual IP as well.
