[Error 90002] Inability to login to EU Data Centers

[Baxnet]

It's still a problem, after I tried every single method on the internet to fix it, also official methods. Still not working, unfortunately. It seems to have a fix from square enix side because as a player u could do nothing with it. Also, my main character is stuck on duty due to DDoS attacks and I can't transfer my character. to any of the data centres. Waiting for fix...

Same issue has there not been any official acknowledgement of this yet ?

Same issue here... kind of.
I can't log in as my main character, however i can create new character on same world (moogle). Probably it's not realted to ddos attack, more likely something went wrong during maintenance and some of the characters became corrupted :/

It seems it's the way login to the servers is handled. I got this after looking at the res mon in windows it is by no means an explanation, merely an educated guess. I have a very short route to the servers (tracert shows 4 hops, 3 of them are my network, around 20-23ms of latency).

I tested with 4 different characters, on the same server. Each world on the DC has multiple IPs and ports to handle connections, this much is logical, for load balancing and whatnot.

Observations so far :

-My characters seem to always connect to the same IP and port (characters are attributed an IP/port combo that changes at set intervals? or doesn't change at all?)

-Char 1, 2, 3 and 4 had different destination IPs and port from each other.

-Char 1, 2 and 3 could connect without issues consistently, but not Char 4.

- I went looking at IPs and ports out of curiosity. for Char 1, 2 and 3, the IP and corresponding port were open.

- for Char 4 port was closed / dropping connection.

It seems it's like a lingering effect of the big DDoS attack or a localized assault on the servers? or maybe network equipment in failsafe/mitigation mode in response to the DDoS/traffic.
Since I think that kind of info is public (with server status website etc) for Chaos - Ragnarok it seems that at least port 55027 for the IP 80.239.145.117 is at fault for not letting people log in, it's the one I could find with my limited testing, there may be more of them. if people could crosscheck that info, it would be a start as to where to look (open task manager, open ressource monitor, under network, pin the ff14 executable and the tabs below will only populate with the related ip/port informations). It could explain why world travel doesn't always solve the issue but DC travel does.

I just checked, I'm on Light currently to play but my char is from Moogle - Chaos, and the IP seems to be almost the same, only the last number (your "117") is different.
In TCP tab, Port (distant) is 55026
So it's quite similar ; I don't know if that helps

On my side it seems the game is trying to connect to this one: 80.239.145.115:55026.

Thank you so much for this investigation I'm about to go to bed, I hope this provides some closure to people though.

From the general thread...I guess it's comforting to know that our characters aren't somehow stuck for a long time.
