The lobby server connection has encountered an error. 2002

Hello,

while I was in Rabanastre, I suddenly lost my connection and got this Message:

Due to a change in your connection settings or the detection of suspicious access to your account, login to your account has been temporarily restricted.

I followed the link, checked my mails and changed my password. ( I guess, I got the messasge, because I bought something with my square enix account after the concert in Dortmund using my smartphone...)

Afterwards, I logged in again through the launcher and when I hit "start" I get the "Connecting to data center." followed by "The lobby server connection has encountered an error. 2002".
I try to get into "Louisoix" on the Chaos Data Center.
(when I tried the Elemental Data Center, I was able to connect, but since I don't have a character there, this is useless to me)
Twice (out of about 19 trys), I could see the followup screen where you can normally select your character. This screen does not show anyone though (only the etheral background), until I once again get the "The lobby server connection has encountered an error. 2002".

I use Windows 10 (PC) in a wired connection.
I have teamspeak, Spotify and Chrome running perfectly fine.
So far, I completely closed FFXIV and restarted first my Router and then my Computer.

Unfortunately, I still get this error.

For those, who have the same problem.
Waiting about an hour "solved" it. (that is: a bit more then one hour, after the error came to first time until now)
(although, now my group is of course done with the dungeon -.-)
