Domoticz report Evohome devices last seen days ago

[jamesb]

I monitor my Evohome HR92s and Controller using Domoticz version: 2020.1 on a Synology DS218play.

It has been good to date. However, 2 days ago contact was lost with the system 4 times. The
The first few times it came back after I flicked through pages on the Honeywell Home app, which took quite a while to start. I went to Domoticz settings and clicked "Apply". Don't know what made it reconnect.
Now, none of that is working.
The devices were "Last seen" 2 days ago.
I tried stopping and starting Domoticz too in the Synology package manager.

Any suggestions please?

Probably better to ask on the Home Automation forum, than here.
