Failed to connect virtual device ‘ethernet0’

It seems this error is still turning up in vSphere 6.5.  I’m running vSphere 6.5.0.5400.

I couldn’t get the VM connected, so after some searching i came across this blog on the VMware community here.

Seems it has something to do with VMRC 9.0.

now if you read the post you come to the comment of Czernobog. at the end he had to use the fat client.  Since you cant connect with the fat client to a vSphere 6.5 i had to use the web client HTML5 not the flash.

Edit the vm en now i could get the vm connected to the network again

Lets hope VMRC 10 comes out quickly or de HTML5 interface gets full features.
