I've you have upgraded to the new AMP Version 126.96.36.199, go and check your IP and Port of your AMP Instance.
I orinally had Port 12000 bound to IP 0.0.0.0. After the Update it changed the Port to the default one at 8080. With this the Auth Server for underlying Instances doenst work. I also couldn't access the webinterface
So how do I fix that?
- Stop your ADS Instance
- Run following Command:
ampinstmgr rebind 'Instance Name'
After that set your IP and Port to your default config and start your ADS Instance. Then it should return to normal :)
