Network Error Bug?

I tried doing puzzles, but the moves can't be played, they are only shown as premoves.

Same here. Firefox 59.0.2 on Linux Mint 18.1, if it helps. But I doubt it is an useragent issue.

Me too, I have this problem (trying to connect to a human, or playing against Stockfish).

Puzzles work for me on iOS app.

Refused to connect to 'wss://lichess.org/lobby/socket/v2?sri=wxj2wrunq6' because it violates the following Content Security Policy directive: "connect-src https://*.lichess.org lichess.org wss://socket.lichess.org:* lichess1.org".

That's the issue. Looks like it should be connecting to wss://socket.lichess.org for the web sockets stuff, but it's connecting to wss://lichess.org for the lobby.

It's always great to see people from 4 different continents waiting for developers to fix their website XD

I'm not having the issue. (Using FireFox 52.7, Debian stretch)

Based on the observation @daves7 made, it's probably one of these ...

Best guess, cause those changes were 15 hours ago, and, Site Update just happened 30 minutes to an hour ago.

@MrCharles thanks.

I've raised an issue on GitHub for it: github.com/ornicar/lila/issues/4253

@daves7

Added details to the issue report.

@revoof is online and is hopefully taking care of it.
