Hi, 

we have some trouble with the Remote Control Skins Service: Remote Server returned an Error: 500 internal server error.

restarting the mgmt services results sometimes in errors that all other services like Enrollment  Agentbuilder, location and activation services have the same error.

On the next test only the remote skin service throws the error.

thus I disabled antivirus temporary, created explizit fw rules according the article https://www.soti.net/mc/help/v15.3/en/setup/installing/system_requirements.html?hl=network%2Cport#ariaid-title3.

We still get the error for the Remote Control Skins Service.

Our Mobicontrol Version is 15.2.3.1033 on premise

DeploymentServerExtension log has the following errors:

Is there a problem with the activate2.soti.net server?

Any other suggestions?

Thank you for your help and a happy new year!
