Unable to Reach Server

[Energon_Universe 6]

Hello, 
 

After updating the application on both TVs and mobile devices, one user somehow lost the email address that was previously bind to the server.

However, none of the users (4 in total) are able to connect anymore.

The public IP is working, and the port forwarding is configured correctly. When I test the connection locally using the external/public IP, everything works as expected.

Before the application update, all users were able to connect without any issues.

I also tried reconnecting two users using their PINs and the email addresses I have on file. The application reports "PIN confirmed", but after approximately one minute, it displays the error "Unable to reach server."

Hi, what Emby app are they trying to connect with?

[Energon_Universe 6]

2 are fromSamsung TVs., and 1 from xiaomi tv box
However, I'll confirm with my internet provider tomorrow whether I'm behind CGNAT.
The last time I asked, I wasn't.
If I'm generally behind CGNAT, it doesn't work for me either when I test it.
I mean, when I enter the Emby IP (Remote (WAN) access) public ip address into the browser.

You didn't mention your OS, if Windows, check your windows firewall... sometimes something about Public/Private gets screwy with Windows.

In the end, it was the ISP. They had switched me back to CGNAT. I changed it back to a regular public IP, and now everything is working fine.

3/3 so far...

Windows 11 pro , I had disabled everything in the antivirus (windows + real a/v software) for testing.
