I don’t know where you got that IP address, but I’m using 38.102.136.138, as indicated in Rich’s screenshots, and it works 1/10 times, but I don’t get Comms failure messages.
Thanks Leigh! Switching to 38.102.136.138 works. I almost always get a Communication Failure message. In case it helps someone else, I’ve found clearing the error message and pressing [F5] is frequently successful.
