I have had this issue quite a bit and for an unknown reason, when I try to login it just gives me this screen over and over and over again. I have tried checking Mojang's end, everything seems to be all good but I cannot join the server. I have searched around and very little is on this except "keep trying". If anyone has any ideas I would love to hear them.

Hey Jack,

Ive started having this problem. I was booted from the server with a connection error and since then this has been happening?

All was good yesterday but as of today it is impossible to join the sever, I tried Force Update like one thread suggested but to no avail. On my end I've done everything I can, at a loss really as what to do.

Got that same error just now. Console log shows some errors with GraviGun+PortalGun but not sure if that is the reason. Don't know any solution yet

I was carrying a gravi gun in my knapsack, not sure if that would cause it.

were we all in an age? cuz it happened to me too now sees time: probably authentication botched up

For clarification, this is on the Ultimate sever, for me at least. I have just read that it might be a corrupted playerfile, which is resolved by clearing that player, which would make me very unhappy if this is the thing.

Edit: Read more into it, is not a corrupted playerfile. Thank God.

Mine was on FTBu but yes I was in an age.

So from what I am reading it is a server problem, no idea really how to fix.

Ok i just checked and i get the same error in ultimate and unleashed but vanilla is fine

seems to have blown over now

Mine still refuses to let me on, not really sure what to do at this point. Perhaps Broonie may come on later and have an idea of the issue.

Edit: I have restarted the launcher for the 40th time lol and all seems to be good now, lets me on the server.
