I have an Attack of the B-Team server that's been working perfectly fine for over a year. We've never had any problems with it and connection in the past has been fine. Recently however, all of us are getting the "Failed to Login: Bad Login" error.
I've restarted the Technic Launcher several times, re-logged in several times, restarted my computer and completed any updates that might have had an effect on it, reinstalled the Technic Launcher and the modpack (just in case). I've done a lot and yet I'm still getting the same error. Same for my friends.
Before the server is online, I keep getting the red text telling me I have the wrong version for the server (telling me I need 1.15.1 or version 1.3). But the server is set to run in minecraft 1.6.4 (and modpack version 1.0.14), which is the one I've been using to try and log on.
I suspected maybe it was just the long queue and aternos was having a bit of a login time out glitch or something, despite me confirming my server, but it seems unlikely.
I've tried looking this up on previous threads but they all seem to be from 2014-2017. Having help and more information on this or more things to try would be greatly appreciated!
