Hi, yesterday I've been playing SK and everything was working as intended, but today I cannot host/join any mission/haven/arcade on Europe region, when I switch to USA everything is working fine but latency is not that great. Every time I try to host/join party "e.no_node_found" error appears in chat.

This is true still. I, too, am only able to go to Haven and/or start parties on US. Likewise is the case for friends. I'll file a bug report in game since OOO might fancy the technical data.
