Dynmap works with localhost but not with Public IP

Hi,

I’ve set up dynmap on my server. My Minecraft server is running 1.16.4 and works perfectly with my public IP after I portforwarded 25565. I installed dynmap but although it works with localhost:8123 and although I portforwarded both TCP and UDP for the port 8123, the dynmap still won’t work with the public IP. Am I doing something wrong? Any assistance would be greatly appreciated.

Hello!

Can you show me your configuration on your router control panel please? And also tell me who your ISP is? If you don’t mind.
