MabiPro: The Authentic Old-School Mabinogi Experience

Came here looking for answers as well, sadge.

I also tried random account names, it doesn't even try to connect or tell me username is wrong, it gives the same message.

Any idea how to fix this?

Yeah I eventually looked for a discord link to join and got told to do that.

But it is fixed now, people can login the normal way again on both channels!
