so i changed my NNID password that was linked to all my nintendo systems (3ds, wii u, and switch) the other day and now my CEMU ca no longer go online with my dumped account.
the log says

Code:
NNID login failed because server response could not be parsed:
[03:44:07] <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<errors>
    <error>
        <code>0106</code>
        <message>Invalid account ID or password</message>
    </error>
</errors>

[03:44:07] IOSU_ACT: NNID login attempt failed

do i have to crank on the old wii u and log in AGAIN and dump the nand ALL OVER AGAIN? -__- or can i fix it from CEMU?
i tried to boot into the wii U home menu from CEMU and that kinda stuff just crashes cemu

You don't have to dump the whole nand for online play via cemu. Otp, seeprom and the certificates are enough.

--------------------- MERGED ---------------------------

OTP and SEEPROM:
"otp.bin" and "seeprom.bin" must be in Cemus root directory.

Certificates:
storage_mlc\sys\title\0005001b\10054000\content\ccerts
storage_mlc\sys\title\0005001b\10054000\content\scerts

In Cemus "mlc01" directory (keep the folder structure, for example "mlc01\sys\title\0005001b\10054000\content\ccerts\WIIU_ACCOUNT_1_CERT.der". Since v1.11.1 the whole folder has to be dumped!

Account data:
storage_mlc\usr\save\system\act\800000 **\account.dat
Replace the stars with a number for the respective user account
The account must be linked to a Nintendo Network ID!

In the directory "mlc01\usr\save\system\act\80000001\account.dat" (always, no matter which number was on top).

Then online play can be activated via the settings.

Then choose the option on the wii u to stay logged in. Idk if it helps. But it is worth a try. Otherwise, redump them, and stay logged in then.

You need to log back in on your wii u. Select save password or whatever it's called. and redump the account.dat.
