OS Name/Version: Debian GNU/Linux 12

Product Name/Version: AMP 2.6.2 - 20250608.1

Problem Description: Roll back bad patch

Steps to reproduce: Not applicable

Actions taken to resolve so far: Unknown

I’ve got the latest patch which broke an instance. How do I roll back from 20250608.1 to a prior version of 2.6.2?

AMP can’t be rolled back unless you took backups externally (such as a VM snapshot), what are the actual problems you’re having?

Running AMP on Debian 12. Installed AMP and then installed L4D2. After L4D2 install and update, the instance hangings on starting. I tried stopping and restarting only to get an error message about the IP address not bound to the app. When I go to the Network and Ports tab, the Application IP Binding is grayed out and set to 0.0.0.0. Underneath that it says, “This instance is not multi-IP aware and cannot be rebound”. I have no idea how to fix this.

Before the latest patch, L4D2 was working fine

Update the L4D2 instance by itself then restart ADS.

I updated the L4D2 instance and restarted ADS. Tried starting L4D2 and it’s still hung at starting. I checked the console and there was nothing in it.
