[arebelof]

Hi,

When I have the Chrome's Device Toolbar active (CTRL + SHIFT + M), I'm getting this error on console when loading the page:

recaptcha__pt.js:805
POST https://www.google.com/recaptcha/api2/pat?k= 401 (Unauthorized)

If I disable the device tollbar, there's no error.

Thank you.

Additionally, I've noticed that when I use Safari dev tools to remotely connect to my iPhone and pull up dev tools in Safari, it seems this error occurs on every load

cududa - thank you for sharing, that totally cleared everything up for me

Overriding the user agent without enabling device mode will still exhibit the same behavior

This user agent value does NOT exhibit this behavior in chrome's dev tools

Yes, different user agents change the in dev tools - but in prod, testing on a real device I still get a 401.

I'm hoping Google doesn't close this issue, as it appears recaptcha just won't load on recent iOS versions and there's no guidance or documentation on the issue.

Seems like the problem start when user agent has iPhone OS 16_0 and above. Its working fine till version iPhone OS 15_8.

anyone has solved this issue please ?

I see this issue on Safari Version 17.5 (19618.2.12.11.6)
Is this because of CORS?

Cross-Origin-Opener-Policy-Report-Only: same-origin;

Also noticing other CSS and JS is returning a 401 response.

I wouldn't expect an answer in this repostory. I opened a discussion in the Google Cloud Security forums If anyone wants to contribute: https://www.googlecloudcommunity.com/gc/reCAPTCHA/reCAPTCHA-initialization-error-on-Safari-iOS-16/td-p/859376

[clark48j]

It looks like this is a red herring error. I was getting the same error on safari and upon investigating the error more on safari on my macbook it turned out once I actually submitted the form I was getting an error about my query string being too long so IIS was rejecting my request. Basically for some reason in safari the getRecatpchaResponse function I had to determine if the user was a bot or not was about 2500 characters long. No idea why it was working in every browser but safari. Anyways I updated the max length of my query string to 3000 in IIS from 2048 and boom it started working again! Hope this can help someone else out but yeah most likely recaptcha is not working in safari due to another reason. Hit that submit button and see what error you get!
