Bf4 error code 1

Hi something I was able to figure out about error code 1 is that if you are trying to get on a specific server and you get the error code 1 let the admin ban you and un ban you. I know it sounds silly but it works. And I host a server for 2 years now successfully with various players that come back each day. Once they receive that error code I do that and they get in easily without problems. Hope this helps.
