Hello, it happens to us on one of our sites with a password, how can I gain access without seeing it in the forum?
I attach errors that come out on the console when it fails.
I don't know how to upload images

Hi,

Could you please provide more info?
Is it happening in your custom code, within your site, or in the preview site? If it's in your site can you provide a test link ?

Regards.
