Why can't I log into the game?

[June62]

I was able to log in just a moment ago, but now it’s not working and says 'The information you have entered is not valid.' Is this a server issue or a problem on my end?

I suppose, DDoS was going (mb still going) from RU IPs and now their authenticating service blockes all ru IPs, sadge
but my friend uses same VPN and could play all these days, mb its connected with provider somehow

adding .dll file using launcher -> mods window helped

Take a look at this; personally, it helped me, but I’m not from the same country as you, so I don’t know if it will help you. You need to add the downloaded file to the Octowow launcher in the "MODS and Add DLL" section.
