Changed Router Setup, can't access UI

Troubleshooting
1

Hello Rockstor,

I was running Plex on my server(at the attic) which was connect to a separate router network at home. Everything worked great on my bedroom tv. But now i wanted to watch Plex downstairs, here my router connection was weak to Plex and had some buffering problems. So instead of two different networks i slaved one router to the other.

Now when i want to access my Plex server downstair its works. But i can’t access the Rockstor UI anymore, I understand that my IP address has changed, now its 192.168.0.10 as its seems at my monitor and router. But when i access it, i get the follow error.

This site can’t be reached
192.168.0.10 refused to connect.
ERR_CONNECTION_REFUSED

Im am able to login into my as the monitor aswell by SSH. Beside this my monitor shows two 'errors’
Failed to start Crash recovery kernel arming.
Scope lib container-3911-systemd-test-default-dependencies.scope has no PIDs. Refusing.

So i was wondering what did i do wrong? And can anyone help me access the UI again.

PS. I earlier also reversed my router setup, but that didn’t work anymore either.

Greetings,

Pieter Iepsma

Http -> HTTPS redirection no longer works. Have you tried https://192.168.0.10 ?

Yes, I did try that, but it made not difference.

Login by ssh as root and review the output of ‘ifconfig’. Find the adapter ‘enp2s0’. If it shows something different than “192.168.0.xxx“ that might be the problem.

There was no enp2s0, but there was enp9s0. This was the output:

enp9s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.0.10 netmask 255.255.255.0 broadcast 192.168.0.255

So says 192.168.0.10, so i get thats not the problem, any other suggestions?

Is the rockstor service running? Output of this command would be helpful: systemctl status -l rockstor-pre rockstor rockstor-bootstrap

Thanks for the response, this is the output:
