Hello all. I have an issue that arises every so often. It happened last night about 3:00 a.m., PHD2 lost pulse guiding to my mount. PHD continued to run and show the guiding graph but no corrective pulses were sent to the mount. I had to restart PHD2 and NINA to correct the issue. My feeling is that it may be an issue with PHD2 since it will become unresponsive at times during these events. 
I use a Mele Quieter 3 on my scope and wirelessly connect to my 10Micron mount. I control the Mele with a laptop wirelessly connected to the 10Micron mount as well. 
Does anyone have an idea of what is going on, or a fix?
Thanks in advance.

Hello Dan,

Maybe not the same issue, but I share what I have:
The wi-fi of my mount could not keep up with the data traffic, even if it worked very well for months. I also have a MeLE which was connected to the wi-fi of the mount and so was my laptop via remote desktop. The issue started suddenly one night when the remote desktop session froze completely. Restarting did not solve it.
At the end, I had to connect my laptop to the MeLE directly via a hotspot open on the MeLE and not through the wi-fi of the mount. In my case it solved the issue (however still not clear why it worked before and all of a sudden it stopped working).
I hope it helps.

Did you check your power management settings in Windows? I assume your Mele is running on Windows 11 (like mine)? In Windows, you even have to check the hardware adapter for power management settings which allows Windows to shut down the device. I deactivated everything.

Maybe you can look into the event viewer for unusual behaviour around your time it happened. Same goes for phd logs around the timestamp. 

regards

Good advice, I will look into those suggestions.
Thanks,

Dan,
Please post your findings if you figure out how to correct the issue.  I have the same error message from time to time.  I'm using a Paramount MYT and get the same pulse guiding error message, even though the Paramount is using DirectGuide.

Total guess but check your usb cables and hub etc.
A meridian flip or slew might be enough to jiggle one lose connection
