I was having a similar issue with my gamedig monitors. I thought it was related to my firewall rules restricting access to these game servers, meaning that uptime-kuma running in a container on the same server wasn't able to access it. That doesn't seem to be the case though.

As a test, I tried to manually install gamedig in my uptime-kuma container using npm install gamedig, and I'm able to successfully query my game servers:

uptime-kuma@36af169156a9:~$ ./node_modules/.bin/gamedig --type dayz dayz.my-docker-network:2302
{"name":"My DayZ Server...
uptime-kuma@36af169156a9:~$ ./node_modules/.bin/gamedig --type valheim valheim.my-docker-network:2456
{"name":"My Valheim Server...

However the equivalent config through uptime-kuma doesn't seem to work:

Didn't find anything revealing in the logs:

2023-03-06T23:20:44-08:00 [MONITOR] WARN: Monitor #17 'DayZ': Failing: Failed all 1 attempts | Interval: 60 seconds | Type: gamedig | Down Count: 0 | Resend Interval: 0

Can you try setting the DayZ port to 27016 in the monitor?

[louislam]

It seems that givenPortOnly set to false, it will work. Or as @chakflying said, using 27016 also works.

https://github.com/louislam/uptime-kuma/blob/2dedc1cfbd2eab61ebcc5793ee4a949532d19405/server/model/monitor.js#L523

I checked the games.txt, there is a value called port_query_offset.

dayz|DayZ (2018)|valve|port=2302,port_query_offset=24714

2302 + 24714 = 2016

What I don't understand here is, what is the point of showing the fake port (2302) instead of 27016?

[chakflying]

I think 2302 is the port that clients actually connect to, while 27015+ is the Valve Server Query Protocol which is used to query the server status. Some info in notes in https://github.com/Yepoleb/python-a2s .

The discussion in #2566 suggested the use of givenPortOnly because server admins would know which port to use. But it seems that now normal users also wanted to use this feature to monitor games they play, and made it confusing.

for mordhau ive tried all ports possible even reinstalling the server changing the ports to its recommended to run the server and still nothing and everything is port forwarded. in console it shows its talking but it ant getting data that its up
