OX mobile api facade error

Hi all,

after successful installation and launching of the facade an the OX Mail app I get the following error, that floods my log-files:

However the app seems to work normal. Sending of Mail works.

Any suggestions? Further information needed?

Is push completely configured and working?

I think I haven't seen such a message and since it is related to something like subscribePush I'm wondering if the relevant endpoints are up and running in the server.
