Problem Description

Issue

This just doesn’t seem to work for some reason, and I don’t know what I’m doing wrong. I just want to get over this hump of why it’s not working. I start it with nothing changed or added and I don’t know what it wants.

Reproduction Steps

• create instance
• start instance
• get told that instance can’t start with Application IP binding set to 0.0.0.0 or 127 etc
• select other options other than those two in the edit settings window of the instance
• try all options and get told that none of them work
• cry, wondering ‘what am I doing wrong?’ to whoever hears you

What options do you get in the ip address dropdown?

[Vector_Impulse]

Default settings with a new instance

[Greelan]

Select 192.168.1.183, that should be fine

[Vector_Impulse]

Ok, I flip it to that IP and now I get this issue.

I try joining the server and it fails

[Greelan]

On your system, run ip a and post the output?

Forgot to mention I have webmin installed too

You don’t have anything else running on the system that is trying to use any of those ports?

Any output from the following (run as root):

ss -tulpn | grep 270

I tried doing port forwarding on spectrum isp app and it turns out I had the port opened for Helldivers 2 a while back, I moved it over to the Amp panel port rules along with tf2.

1. I tried on a fresh instance
2. started it
3. it needed the app ip binding to the ip address
4. switched it over, restarted when asked
5. started it, it was fine
6. shut it off
7. switched the starting map to an MVM map
8. started it back up, it started fine
9. I shut it down
10. I put in the Game Server Login Token
11. start it up
12. instance won’t start anymore and it still looks like this

oh and the ss -tulpn | grep 270 came back blank when I ran it as root

[Greelan]

Has the GSLT expired? Was it generated for the right app id?

[Vector_Impulse]

I regenerated it just in case and it’s the right app id (440), still nothing

[Greelan]

Did a bit of testing myself. Seems with MVM maps you need to increase the player limit to 32 (to allow proper bot spawn, because they are counted as part of max players). When I did that, it was fine

[Vector_Impulse]

holy moly, that was it! That worked! Thank you for your time!
