Have you checked things like free disk space 3GB or more ?

Hello @gareth.blakecoggins,

I have checked on all the vms and they have sufficient disk spaces. 

I think I found the issue, maybe it is our network something is blocking it. It shows Server Unreachable.

My next suggestion after confirming hard drive space is / was network connectivity 

Drill into one of them and click the following. it should tell you why it is not compatible

Hello,

If you are unable to determine the reason for the devices showing as incompatible by using the Compatibility Checklist, then please open a support ticket through our Customer Portal so an engineer can assist.
