I found a solution to this. The value under this registry key has to be increased:
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WSMAN\Client
Reg DWORD maxEnvelopeSize, increased to 8192. If the entry does not exist, create it.
(I guess increasing to 600 from the default 500 would also work but I have not tested it)
to check the updated setting run power shell:
Get-Item -Path WSMan:\localhost\MaxEnvelopeSizekb
as soon as I did this, all servers started coming online
