strange event log message from HH5

My HH5 reconnects regularly, at least once a week. I took a look at the even log this morning and was puzzled by this entry which happened twice:

07:41:12, 25 Oct. (1105748.290000) CWMP: session closed due to error: No response
07:41:12, 25 Oct. (1105747.890000) CWMP: Server URL: https://pbthdm.bt.mo; Connecting as user: ACS username

What is this URL it is trying to connect to and why should it fail?

I believe this is your HomeHub doing a firmware / software /config update check via TR-069. I'd imagine it's failing due to something at BT's end.

hmm, I kind of guessed so. If I try to access that URL from a web browser it just hung...

The end of the server name is truncated in the log. It is actually motive.com
