New account creation succeeds, login fails with error 265

[ggrekhov]

Unreal Tournament 3 login via OpenSpy worked for me a couple of days ago, but since yesterday all accounts fail to log in.

I reproduced it with a brand-new account.

Account creation on TCP 29901:

C -> S:
\newuser\\nick\TestAccSucLogFa\...\uniquenick\TestAccSucLogFa\...\gamename\ut3pc\final\

S -> C:
\nur\0\pid\10170372\final\

So account creation succeeds and OpenSpy assigns PID 10170372.

Later, login on TCP 29900:

C -> S:
\login\\...\uniquenick\TestAccSucLogFa\...\productid\11097\gamename\ut3pc\namespaceid\64\...\final\

S -> C:
\error\\err\265\fatal\\errmsg\The uniquenick provided was incorrect.\id\0\final\

The uniquenick is exactly the same as the account that was just successfully created.

Older accounts that previously worked now fail with the same error.

DNS/TCP connectivity is fine and both services respond normally.

It looks like account creation/profile lookup on 29901 succeeds, while GPCM login on 29900 cannot resolve the same uniquenick.

Could there currently be a backend/profile lookup issue between these services?
