Everything is working good just that I am not able to use the OH Cloud instance via domain name.
I can access it over IP address from outside.
However, I am able to access the test site over HTTPS on port 80 using the domain name.
I am using Ubuntu and opened port 3000 as required in firewall.
I have checked the listening ports and can see that port 3000 is opened and listening via TCPv6 instead on TCPv4.
Can someone please help me out in resolving the issue?
Ok, I got the issue.
I forgot to copy the Server block in nginx config file. Copied server block and removed 3000 from my firewall and it is working as expected now.
