Hi guys,
I dunno if I'm missing something super obvious, I have downloaded technic launcher, then downloaded the above mudpack, installed it on my aternos sevrer, started the server and then added my server address when given the chance. My issue is every single time it tells me "Failed to connect to server: Failed to login, invalid session, try restarting your game (which I have done numerous times) I have even tried wiping my server and completely reinstalling everything to no avail. Anyone run into this before?
