I logged in around 9 pm PST and it showed error connection timed out. The problem persists even when I switched to my mobile data from my home WiFi. So is the website down for some servers or do I need to tweak something in my internet connection?
I'm guessing that you are in Japan, or in a country near Japan? There was an issue with the server that handles renshuu connections in that region (and passing them along to the main server), but it should be resolved now. I'm really sorry about the inconvenience! First time since I set up that server years ago that it has had issues.
