I'm getting the same error now! When I try to log in from the main play.sindome page, it just continuously loads and says "Waiting for play.sindome.org..." and when I try to connect manually through the client, the status says UNEXPECTED ERROR EMFILE and doesn't recognize my username/password.
The webclient has some issues, I'm testing fixes on them now (as some of you know). Hopefully within a few days we'll roll out an update that fixes this issue for realsies. Thanks for the heads up about the issue!
