There is now a new connection method available, which should hopefully make things more stable. It is still in a testing stage, but anyone can already enable it by simply typing "/connectiontype ws" in chat (no quotes).
To revert back to default type "/connectiontype sr" and to check the current status type "/connectiontype". For changes to take effect you need to reload the page. Please post you feedback here!
Thanks everyone for helping with testing, it was worth a try, now back to the drawing board!
