Deployment: Cannot connect to RAT server

[FabianSIK]

Hello Community,

I have a strange error since this morning. The IP-Address was changed on the machine. Since then we're not able to deploy the HMI to the Nexeed system.

Any thoughts?

Is it a system with V2 Image ? If yes, then please check the security manager...

Maybe your certificates are not valid anymore, because of the new IP address ?

Hi,

thanks for the swift reply. Yes, we use v2. The certificates are not revoked. The popup doesn't show any information.

As the error message states: we do not get a connection to the RAT server on the machine. The funny thing is, the machine next door doesn't has the problem.

It took a while but we figured out that the IP-Address-change did indeed cause the issue. There seems to be another participant with the same IP-Address. The funny thing is, that we are able to login with TwinCAT and remotly connect over RDP.

Maybe this helps someone with the same issue...
