Which VPS provider you are using. If it is amazon, you will have to create security profile to allow incoming connection to 27879. Digital ocean and vultr are allowing all incoming connections by default.
I'm using Google cloud platform.
I am sorry, I have never used them. Do they have firewall configuration somewhere?. Is it a windows VPS?. If yes, check the windows firewall configuration. After starting the client, you can use ping.eu to check whether the port is open.
Its windows VPS. I did find firewall and advanced firewall settings.. but do not know how to go from there.
Right click on the network icon on the task bar>Open network and sharing center>Click Windows Firewall>Turn windows firewall on or off>select "Turn off Windows Firewall" for Public network
Sorry it did not work out. thanks. I will google and find some solution.
Ok, got it. First enable the firewall as before to be more secure.
Right click on the network icon on the task bar>Open network and sharing center>Click Windows Firewall>Allow an app or feature through windows firewall>click allow another app>browse for the goatd-qt and add it and then click OK
