Velux binding after upgrade openhab 3 (Docker)

Hi,

Since the upgrade to 3.0 I get this error every few seconds:


2020-12-24 22:29:24.979 [WARN ] [x.internal.bridge.slip.io.Connection] - io() on 10.0.2.137: raised an error during connection setup: No route to host (Host unreachable).
2020-12-24 22:29:24.980 [INFO ] [x.internal.bridge.slip.io.Connection] - io() on 10.0.2.137: socket I/O failed 5 times.
2020-12-24 22:29:24.980 [INFO ] [nternal.bridge.slip.io.SSLconnection] - Starting velux bridge connection.

Any hints?
Thanks and merry Christmas!

Daniel
