Issue with TF2 and Gmod servers installation and running

[JagerPup]

Operating System

Windows Server 2019

AMP Version and Build Date

latest

AMP Release Stream

Mainline

I confirm that

• [x] I have searched for an existing bug report for this issue.
• [x] I am using the latest available version of AMP.
• [x] my operating system is up-to-date.

Intended Action

I have tried everything from reinstalling AMP to opening ports and reinstalling the servers for gmod and team fortress 2 and it can't start the server i keep getting this error - i have no issues with minecraft or palworld starting they work but can't get Team Fortress 2 or Garry's Mod Servers to work and start

Application Error A fault is preventing the application from starting. Manage the instance to examine the logs.

i look at the logs and get this error

[02:59:26] [Core Error/7] : SocketException [02:59:26] [Core Error/7] : [0] (SocketException) : The requested address is not valid in its context. [02:59:26] [Core Error/7] : at Net.Sockets.Socket.UpdateStatusAfterSocketErrorAndThrowException(SocketError error, Boolean disconnectOnFailure, String callerName) at Net.Sockets.Socket.DoBind(EndPoint endPointSnapshot, SocketAddress socketAddress) at Net.Sockets.Socket.Bind(EndPoint localEP) at RCONPlugin.UDPlogger..ctor(IPAddress ListenAddress) at GenericModule.GenericApp.SetupUDPLogger() at GenericModule.GenericApp.SetupProcess() at GenericModule.GenericApp.DoAppStartup(Boolean IsUpdating) at GenericModule.GenericApp.Start()

---

Am unsure how to fix any help would be appreciated

Expected Behaviour

The server to start like the minecraft and palworld servers

Actual Behaviour

Can't start the servers Errors and not sure how to fix

Application Error A fault is preventing the application from starting. Manage the instance to examine the logs.

Reproduction

Not sure

[JagerPup]

i tested it works fine if i use a start.bat file to start the servers but if i use the AMP system it will not bootup the Garry's Mod Servers Or Team Fortress 2 Servers - not sure how to fix this error so please help

What IP do you have selected when you click the pencil icon for that instance and go to the network tab?

[JagerPup]

I have the main selected it will. Bootup through a bat file but not the main program

i selected every ip and still the same errors

[IceOfWraith]

Are you running this over a VPN? Do you have a static IP set on your server?

[JagerPup]

it isn't hosted on a vpn i even tried on a different machine same errors

[IceOfWraith]

Do you have a static IP set on your server?

[JagerPup]

yes

[IceOfWraith]

Share a screenshot of the "IP Address Pool" option by searching for it in the top right of AMP.

[JagerPup]

the weird thing is Minecraft servers and palworld servers will run it's just any server that uses srcds won't for some reason

[IceOfWraith]

Not weird. There's certain logic needed to run SRCDS servers that the others don't have.

[IceOfWraith]

Gotta get that screenshot to move forward though.

[JagerPup]

what would you like a screenshot of the logs

[JagerPup]

[JagerPup]

AMPLOG 2025-08-02 20-50-50.log

This^

[JagerPup]

[IceOfWraith]

Delete everything in there. Then restart AMP. Share the screenshot again.

[JagerPup]

same info

[JagerPup]

nothing changed in the screenshot

[IceOfWraith]

Click the pencil icon for one of those instances and under the Network tab turn off "Use Host-Mode Networking" and see how it behaves.

[JagerPup]

it is greayed out won't let me turn it off

[JagerPup]

ok i got it to turn off on a new instance but it still throws a error

[IceOfWraith]

Yeah, that shouldn't matter actually. Got mixed up with another support thread. I'm trying this on my end to see how it behaves.

[JagerPup]

ok

[JagerPup]

not sure why tf2 and gmod wants to throw errors wish they would work because they work fine in a regular .bat file to start the server and it allows players to join so not sure what is different

[IceOfWraith]

You can't really compare the two. AMP functions extremely different from the .bat file. AMP uses the RCON and monitors the UDP logging function of the game servers. And it's in those that the original errors are coming. But that latest log you shared is different yet again. So I'm not quite following where the issue is for your setup yet.
