This is occurring with the Openspot connected to REF001C.

So, all of this appears to be new behavior on the TH-D74, although I just got a TH-D75 today and am seeing the same thing. I've successfully used the older TH-D74 for QSOs on REF001C.

I'm running the latest firmware on an Ethernet-connected Openspot 1 configured to connect to REF001C.

The connector is in fact connected to the reflector according to the main page.

On the radio, I'm transmitting in DR mode with a TO call of CQCQCQ and RPT1 and RPT2 as DIRECT.
My call sign is correctly set.

When I key up and ID, I see on the Openspot log that my transmission is being picked up by the Openspot. Once I release PTT, the log finishes logging the transmission, and about ten seconds later the Openspot announces that it's connected again and re-connecting to the reflector.

Any ideas as to what's happening? Could it be something transitory with REF001C?

(edit)
So, I'm seeing the same thing with REF030/E, so I don't think it's a single reflector.

I've also tried with my OpenSpot 3, and see the same results.

Here's a log:

OK, looking at the log, it looks like it's timing out for some reason. Thoughts? My timeout is set to the default for the reflector settings, which I think is 30s.

FWIW, this is on a wired network to a cable modem backbone. The Openspot does appear to be connected to the reflector. I've also tried a second network (cell phone hotspot) to no avail.

Here's a screenshot of the settings:
