Not having this issue, this kind of error is generated when there is a backend error, or trouble connecting to the server on attempt to generate the QR code.

Double-check your error logs as instructed in the issue template: https://github.com/danny-avila/LibreChat/issues/new?template=BUG-REPORT.yml

@skapytek did you set this ENV? process.env.CREDS_KEY

[gbzret4d]

CREDS_KEY=pw8p8tuqjw84sbx0b416iy68z2q5ney9a86aip5zkxp5a2ywdekkeod314qvgj4h

[rubentalstra]

as you can see here. that it's indicating that it can;t load the:

const key = Buffer.from(process.env.CREDS_KEY, 'hex');

[gbzret4d]

Im not sure what caused this since the correct settings were set in the .env file.
Ive recreated all librechat containers and now i was able to set up the 2fa.

Works for me on iOS safari with the light theme.

I am using docker for librechat.
