Failed to Connect to net-secondary.web.minecraft…

Hello Guys,

I am very new to this Docker Minecraft Server Topic. In the last time the Switch from my son was the Host for playing Minecraft together , then i read about Docker Minecraft Server.

How i to run the Server:

I have a QNAP NAS and installed the Container with Network Mode Bridge for getting a static ip.
This works with a Virtual Switch. I think i have Problems there with the Port because i get the error Message according to the picture.


It is Not possible to Download the Software because of Port 443. i additionally have run Home Assistant over this Virtual Switch and there i have no Problems.

Does anyone have a Hint for me? If i start the Container in NAT Mode then the Server Starts but i dont find him in my Network.

Maybe additional pictures may help?
I also Can see that there is a portforwarding if i start per NAT but Not in Bridge Mode.
But i have No Option in Bridge mode to forward ports.


Greetings and thanks!

Start by reproducing the QNAP setup with Docker in bridge and NAT network modes, focusing on the reported port 443 failure and the difference in port forwarding. Compare the container network settings and the Home Assistant setup. Done means identifying the cause of the connection failure and documenting a confirmed working configuration.
