I changed my ports from 8096/8920 to 41738/49738 and now my emby server is NOT accessible

In an effort to be non-intuitive and obscure brut-force attacks on my emby server, I changed my port from 8096 to 41738 and 8920 to 49738.    After saving the changed, I restarted my server and now I cannot access from my LAN via the IP:41738.    

I have changed the rules on my router for WAN access, and cannot access that way either.     What did I do wrong?    How do I recover from this?

Hi, what ports exactly did you change?

Ok, so I solved my own problem.     Well, I should say, ChatGPT was able to guide me to solve my own problem.   I am using CentOS, and there is a firewall running under the hood.

 

Check firewall status

sudo systemctl status firewalld 

List currently open ports

sudo firewall-cmd --list-ports 

Open your ports permanently

sudo firewall-cmd --add-port=41738/tcp --permanent
sudo firewall-cmd --add-port=49173/tcp --permanent
sudo firewall-cmd --reload

Once I reloaded, I tried accessing again and voilà ... it works again!

Thanks for following up.
