I had problems between the end of April until last weekend. Since my openHAB installation was not updated during this period, I strongly believe that the problem was caused by an OS update. The problems started after I received an OS update and disappeared after another one. So my understanding is that the problems should be independent of openHAB and a router. It’s just a guess, but updating the OS as soon as possible can’t be wrong. I appreciate feedback if anyone has had the same experience.
