Daikin binding - Could not start Jetty http client

I’m getting these errors whenever I start OH2:

This happens 90% of the time (the other 10% OH2 starts without these errors).
My environment:

  1. QNAP NAS (Intel CPU)
  2. OpenHAB 2.5.0
  3. Java Development Kit 1.8.201

Edit: if I remove my items file from the items folder, start OH2, and then copy items to its folder, all is Ok. But this is not a solution.

Does it happen only during startup?

Yes, during startup only.

Then this is probably due to the services not starting in the same order everytime and some of them are not quite ready. I would ignore

Thanks
