Everytime I Run Test I get errors saying: 'Test failed. All selected Load Agents were disconnected. The Wait Operation timed out. [0x80070102]' and that my local host has no connection. Before I start my test the status of my servers are online and only when the test fails that it tells me that it is offline. I have also tried to remove, add the servers and reset the connection but no luck. Please advise what I should do?
