[mercedesme] Websocket Exception: Reason: {0}

[joerg1985]

The Mercedes Me Account does show "Websocket Exception: Reason: {0}" and is kind of stuck in this state. The logs show the real issue [rcedesme.interna l.server.MBWebsocket] - onError Failed to upgrade to websocket: Unexpected HTTP Response Status Co de: 412 Precondition Failed

There is no way to reset the Account. Two weeks ago the refresh if the token failed and i had to delete Account from openhab and recreate it, now again.

Expected Behavior

The placeholder inside the log should be resolved. And there should be a way to reset the Account, e.g. like the Zigbee Binding does, this a switch hidden in advance settings of the thing.

Current Behavior

Possible Solution

See above

This is not fixed with #18115 the PR does not handle this https://github.com/openhab/openhab-addons/blob/main/bundles/org.openhab.binding.mercedesme/src/main/java/org/openhab/binding/mercedesme/internal/server/MBWebsocket.java#L122

I am currently testing a fix for this and other issues related to this MBWebsocket class.
