[Zommerlion13]

So I got tekkit classic around 5 days ago. It was all fine until yesterday. I couldn't get on to the minecraft server. It kept on saying Offline and would you like to play offline mode I tried fixing it nothing worked. Then i waited a day when i came back it came with a different problem it said http://prntscr.com/d82m52 I looked at around 4-6 videos on how to fix i tried reinstalling java creating new Microsoft account reinstalling technic launcher but nothing works! Please help me i want to play on tekkit classic but it just won't work. I can't even now get passed the login screen. Please help.

Microsoft account? They own the game, but they are not the developers. Mojang is

Can you get into the Mojang Launcher?
