Google Recapcha not work on all CWP servers.

We have dozens of CWP servers running version 1.18.
All servers are experiencing the same issue. Google reCAPTCHA on the sites hosted on these servers frequently returns a timeout error. (These are all different PHP-based sites; while reCAPTCHA does work very occasionally, it mostly triggers the following timeout error):

[Sat Oct 10 14:06:03.963742 2026] [proxy_fcgi:error] [pid 3726163:tid 3726196] [client 78.167.3.196:27106] AH01071: Got error 'PHP message: PHP Warning: file_get_contents(https://www.google.com/recaptcha/api/siteverify): Failed to open stream: Connection timed out in /home/USER/public_html/app/lib/vendor/google/recaptcha/src/ReCaptcha/RequestMethod/Post.php on line 80', referer: https://www.USERSITE.com/

NOTE: Increasing the `default_socket_timeout` value in `php.ini` does not resolve the issue, as that does not appear to be the root cause.

Out of curiosity, who is your host/bandwidth provider? Is this a new occurrence or has it happened in the past? Is there any pattern to the time of day? And have you done any PHPi-FPM tuning to the servers?

Host/bandwidth provider: Contabo

This issue has emerged recently (specifically after switching to AlmaLinux 9). All of these servers were either reformatted and reinstalled recently or are brand-new servers that were set up from scratch.

At first, I thought the problem stemmed from using CloudFlare, but the same issue occurs on sites that do not use CloudFlare.

I haven't identified a specific time interval; the problem seems to occur at completely random times.

I do not believe the standard adjustments I make to the PHP-FPM .ini files are causing this issue (I generally increase values ​​like `max_execution_time`, etc., and I have been applying these same settings for years).

The fact that the issue affects all PHP-FPM versions suggests that the root cause lies elsewhere.

Also, when I check via SSH, I see there is no issue accessing the reCAPTCHA servers.

Curious why not use the built in Google Authenticator 2FA?

No editing code that could change with an update.
