PlayStation realms

Cannot connect to realms on any PlayStation device. Searched about problems with realms and people are having problems getting on to realms at the moment. The realm that I ply on consists of people from Xbox PlayStation and pc. I can't get on with any of my devices and I also can't get onto my own realm. Tried resetting/ deleting. Not an internet issue can play any other online game and have anywhere from 50-100 mbps.
