device forwarding doesn't work anymore (was working thursday)

[EastEriq]

Lipp servers started correctly on last11e and 11w. Logger on 11w periodically succeeds in probing focuser 3 and 4 as well as camera 3 and 4. However

>> Unit.Focuser(3).Pos
17:03:07.880 [INF] [pid=1363183] Remote.send: sending URL='http://127.0.0.1:8000/last/api/v1/focuser/3/Pos'
17:03:08.001 [ERR] [pid=1363183] Error: 'HTTP/1.1 500 Internal Server Error' (Url='http://127.0.0.1:8000/last/api/v1/focuser/3/Pos')

Ditto with 4 and cameras 3 and 4. 1 and 2 work regularly when queried on 11e.

Conversely (tried in the uvicorn webby for a change), 11w can query its devices, but not focusers, cameras 1 & 2 nor mount.

More on this in the stdout lipp log, e.g. querying focuser 3 from 11e:

Same traces (except for the counter of RequestId) when querying other other side devices, from either machine.
