Hello,
Thank you for your patience.
We’ve checked the error log, and this issue is usually caused by some plugin on your website not using the latest version of the Guzzle HTTP library and using a very old version that doesn’t include a fix to handle custom headers.
You can verify the same by performing a plugin conflict on the website and keeping only the Instant Indexing API plugin enabled try to submit a URL: https://rankmath.com/kb/check-plugin-conflicts/
You can then start enabling the plugins one by one to check which one is using the old version of the library mentioned above.
Hope this helps pinpoint the culprit.
