Ok now please trust me I tried all the available ways on internet and I am 90% sure that this 3 things are issues with zorin os.
You can't ping external ip or host it will show error
ping: sendmsg: Operation not permitted
You can't traceroute ip or hostname again the same error
Ssh client doesn't works just connection timed out. I am able to connect from windows and now please don't give me all that stuff that you mistyped or that your server don't have port 22 opened I know all that stuff.
So I would like to ping @AZorin and @zorink (Sorry If mispinged) for attention on this things.
I also don't know the solution the solution was that it is a issue and maybe zorin team will look into it.
If you want to help me please give me the output of ping zorin.com so that I can confirm that operation not permitted problem happens with everyone not only me.
I'm not sure I have much to input here. However if it were I, to rule out my desktop setup, I'd set myself up a like desktop inside a VM. Don't install anything extra on your VM desktop. From within your VM desktop, Open a terminal and run ssh [whatever-user]@your-server-ip-address -p [whatever port you're using]
If you can connect without issue, then you can safely say, something with your network stack has got jacked somewhere along the way.
