Maestro suddenly does not "see" the 6600M

I used the rig last night and this morning the 6600M says it can not find the radio. I know the radio is ON. I can turn it ON and OFF the radio by remote control and it works with the SDR software at the remote computer. I believe this should prove that the radio is actually working.

The Maestro has an IP from my network on wifi. I did go to the Log In on the screen because the white man to right would not come up and identify me. I correctly enter the username and password. The white box then says "ok" and that's it. If I press the white man, the Log In box reappears. Is this proper? Am I doing anything incorrectly?

Does this make sense to anyone. Thank you for any assistance.
