Hello,

For the past 3 days I've been having issues logging in on some characters, and even accessing some data centers. I'm based in Germany, Europe.

Here's how things were yesterday:
- I can access the Chaos and Elemental data centers
- I can log in on character A on Cerberus (Chaos) without any issue
- I can log in on character B on Carbuncle (Elemental) without any issue
- When I try to log in on character C on Cerberus (Chaos), I get stuck on the "Now Loading" screen for a while, and get either the 90002 or the 10105 errors.

However, if I log in with character C on a different server (Sagittarius), then I don't experience those issues (but logging out on Cerberus and attempting to log back in results in the same problem).

Today things were slightly different:
- I could not access the Chaos data center (errors 2002 and 10105), but after switching to Gaia (which I could access without any issue) and back to Chaos I managed to log in
- When I try to log in on character A on Cerberus (Chaos), I get stuck on the "Now Loading" screen for a while, and get either the 90002 or the 10105 errors.
- I can log in on character C on Cerberus (Chaos) without any issue.

Logging in from another server (Sagittarius) still worked for character A.

I tried resetting my router as well as the advice given here but it's still happening.

What I find quite strange is that 2 characters on the same data center and the same server don't have the same behavior, and that behavior is not consistent either, since now A has problems when C was the one causing issues yesterday.

I'm not sure if this is worth reporting as a bug, but I would appreciate any advice on the matter.
