Issue Server down after restarting Plesk

[othmaqsa]

Server operating system version

Ubuntu 20.xx.xx

Plesk version and microupdate number

The last version

Hello,

I restarted the Plesk server from the Plesk UI interface, and since then, I no longer have access to the Plesk interface, the website is down, the webmail also. I can no longer connect to the VPS via SSH.

I can only connect to the KVM console.

Any idea please?

Either several services are not running or a firewall is blocking the ports.

Please how can I check this for the Kvm console ?

@Bitpalast , another remark: when I log in through the Kvm console, there is no internet access, so the no connection is allowed outside, I can't update the packages, I can't do nothing.

... or a firewall is blocking the ports.

Did you check it?

Did you check it?

Yes, the problem is when I have typed a cmd to disable the firewall, it look like a file need to be downloaded, and as there no Network access, the cmd failed.

I have a received a response from the support team (attached screenshot)

@Bitpalast , can you help ?

 

[Bitpalast]

I think the best starting point is to disable the firewall service. However, I am not familiar with Ubuntu. I think on Ubuntu it is not firewalld, neither iptables, but something different. I am not sure.

I have finally solved the issue.
The root problem is the Firewall.

@Bitpalast I don't know if I should reactivate the Firewall, the fact that it caused a server crash.
