[SOLVED] No DNS? when Docker Container in VLAN Network

[Blackbird2k]

Hello,

 

I have tried to set up a Factorio GameServer (template from here). When I have the Docker container on the normal bridge network it seems to work as well. However, when I try to put the Docker container in a custom VLAN network I see the following errors in the LOG.

 

0.741 Checksum for script /factorio/temp/currently-playing/control.lua: 3931528263
0.741 Info UDPSocket.cpp:27: Opening socket at (IP ADDR:({0.0.0.0:34197}))0.741 Hosting game at IP ADDR:({0.0.0.0:34197})

11.260 Info HttpSharedState.cpp:145: Downloading https://auth.factorio.com/generate-server-padlock-2?api_version=4

11.260 Error ServerMultiplayerManager.cpp:90: MultiplayerManager failed: "Failed to reach auth server. Code: 520. Error: Could not resolve host: auth.factorio.com."

 

I also tried to google the error but it didn't really help me (at least not in the context of Docker). But if I'm looking at it correctly, I would say from the LOGs that DNS is not working correctly. Does anyone know this or a similar error?

The problem was in the firewall settings of my UniFi USG.

I am having this same problem! Been trying to fix it for a MONTH! It was working fine with my UniFi USG, but then I changed ISP's and it won't work. I'm sure something needs changing, can you give me any hints what did it for you?
