Problem finding out MQTT credentials #7

I'm running KX-Bridge in a docker container on a server in my LAN, and tries to extract the printer credentials by running Anycubic Slicer Next on my Debian workstation.
This is part of my output. I left out the blocks with Device-ID and IP, those doesn't seem important right now.

`bjorne@iMacDebian:~/KX-Bridge-Release$ python3 ./extract_credentials.py --verbose
[] Searching for AnycubicSlicer process ...
[
] Process found: AnycubicSlicerNext (PID 7467)
[] Reading process memory ...
[
] 1131 memory segments read (1537.9 MB)
[] Searching for credentials ...
[
] Scanning ... 100% (1538 MB)

=======================================================
RESULTS

Username userE2lVGB4r (matches: 32)
usernameFragment (matches: 21)
userAgentData (matches: 9)
userSpaceOnUse (matches: 7)
userCertificate (matches: 7)
userInputDate (matches: 7)
userInputTime (matches: 7)
userWantsControl (matches: 6)
userJoinNotify (matches: 6)
usermodehelper (matches: 6)
Password 15AnalysisManagerIS2 (matches: 2907)
stringIcSt11char (matches: 2215)
6detail9PassModelINS (matches: 2168)
7userDataDirectoryEv (matches: 1002)
formatterINS0 (matches: 702)
15AnalysisManagerIS1 (matches: 581)
15MachineFunctionENS (matches: 546)
startP2PConnection (matches: 512)
13normalizedNFCERKNS (matches: 501)
ZNSt14numeric (matches: 482)
`

The username return when not using --verbose gave me the second one, usernameFragment. Verbose gives a better list, the first hit with 32 matches seems legit.
But none of the passwords seems correct. I've tried all of them with no success.

Do I do anything wrong, or does my printer not wanna play nice with the nice extraction tool?

Never mind, restarted ASN and tried yet again to extract the credentials, and this time I got a password that works 🥳

Now the WebUI shows as connected, and the printer status reports as ready. But no temperatures are reported, and nothing happens when I push on buttons and stuff. The adventure continues, but with a new problem 😆
