Originally assigned to: @maziggy on GitHub.

Bug Description

I tried logging in to Bambu Cloud in the Profiles Section of Bambuddy.
Upon entering my double-checked credentials, I am asked to put in my verification code (that is said to be sent via mail).
Referring to my mailserver there is no attempt from Bambu to send me an email with the verification code (I checked if Bambu mails themselves arrive).

The Login then fails with the error "Verification failed".
Trying to enable debug tracing shows, this doesn't produce any logs for me to debug further.
Docker logs also do not produce any errors.

Expected Behavior

Steps to Reproduce

  2. Try to login to Cloud Profiles via Username/Password
  3. Enter Verification Code (TOTP) since there is no mail sent
  4. "Verification failed" pops up

This is definitely working. You'll receive an emai from noreply@bambulab.com with subject "Bambu Lab Verification Code". Error cause must be your email setup.

Perhaps BL currently has an outage. Don't know.

Just tried again and it works. But I'm using 0.1.6-final. Try it.

Have been trying to log in for quite some time now (maybe two weeks) and it wasn't working with the same error.
Did dismiss it up until now.

Since it repeatedly worked with disabling 2FA via TOTP now, I guess this is some shenanigans on Bambus side with accounts being not the same as accounts.

Will try 0.1.6-final asap and report back

Just built 0.1.6-final from source, started it and it fails with the same error.

Disabled 2FA in Bambu Account -> Mail delivered -> Login works.
Enable 2FA in Bambu Account with TOTP -> No Mail -> Trying TOTP -> Verification failed

Also checked timezone of my browser, TOTP-app and server.
Verified, that Bambu sends me mail when logging into the website and accepts TOTP (when enabled) on the web-login.

I have the exact same problem. Without TOTP activated, Cloudprofiles work. Activating TOTP and trying to log in from Bambuddy -> not receiving any Mail. Im using an iCloud-Mailaddress which is confirmed working. Problem exist in 1.6 aswell.
