Error 5003 constantly appearing [Leviathan]

Yesterday as I waited on queue and receiving around 2-3 2002 errors, I started to get a lot of 5003 errors. Thankfully I did managed to get in the game despite being peak hours, but it was a bit annoying to see it pop up.

It was something about an authentication error, and even when I tried to connect to the data center before I went to bed to see how the queue times were at that point in the night-- I still got it.

Not sure what was going on but I hope that error goes away soon- It honestly gave me a scare thinking it was either my account or something.

I'm sure the devs are doing their best to make things smooth, but I felt like reporting on this because it was quite odd to have so many errors of that nature every 10-15 minutes after 5:30pm EST
