victron connect app (android 13) fails to reconnect mqtt after some idling - R2 error

following issue is perhaps known already:

the connect app being connected to a smart solar 250/60 via vrm.

after some minutes with the connect app in the background it fails to reconnect. re-opening the smart solar leads to an error finally.

a new connection is only possible after closing and reopening of the app.

Does it only happen to me!?

The error reads "Unable to connect to the RPC broker.. Error Code: #R2"

I prepared a screenshot.

Oh, I forgot the version: VictronConnect v5.96.

The issue appeared in previous versions already, but I regarded it as too obvious it would survive an upgrade.

The issue appears when connected via vrm/installation/devices. Leaving the app open and idling in the background leads to "#R2".

I will re-check and report the behaviour in a local (bluetooth) connection.

Shutting down VictronConnect and starting up again works.
