When I try to play multiplayer (connect to any server or start a new server online) the game displays text "Wrong WEB password". Where is the mistake or is it bug?

Last time I played multiplayer, over a month ago, it worked just as usual.

Wrong WEB password? That's new. Wrong game password would make sense,in that case you could login in lfs.net and change it.

I changed both passwords and now it works fine.

good
