Error: cURL error 6: getaddrinfo() thread failed to start error

Thanks for reaching out and sharing screenshots of the issue. As Site Kit was working for you previously if you’d like to share the following information I’d be happy to check your setup:

1. Your Site Health information. You can use this form to share privately.
2. Do you see any errors or notices when checking your Site Health status – which differs to your Site Health information above. I ask as the “JSON” related error on your primary Site Kit dashboard is a general WordPress error.
3. On your Site Kit dashboard whereby you see the “Not a valid JSON response” are there any browser console errors?

If something wrong with the Google Site Kit plugin please fixes the issue or advice me on what and how to do it.

Once we have the above information we may be able to determine more on this. cURL errors are typically hosting related although you may have third party plugins impact Site Kit functionality. I’ll provide some suggestions once we have the above information.

Let me know if you have any questions on the above.

Many thanks for sharing the additional insights. As you seem to be using some plugins which may have configurations that could impact Site Kit functionality can you follow the steps below and share whether you encounter the same notice or error?

1. Login to your site from a Chrome browser incognito window
2. As you already have the Health Check & Troubleshooting plugin active navigate to “Plugins > Health Check & Troubleshooting > Troubleshoot”
3. From the same screen click on the “Available Plugins” tab at the top right and then click on the “Enable” option next to “Site Kit by Google”
4. Browser thought your Site Kit dashboards or check for the same notice once more

If the same notice occurs please share on what screen or at what stage you see this “cURL error 6: getaddrinfo()” notice, and share any console errors on that page.

Hi @humanist1,

Great that this cURL related error no longer occurs, thanks for performing this check! Considering it no longer occurs what you can do next is enable your other plugins one by one while remaining in troubleshooting mode, checking for the same error message each time.

I ask the above as it seems there may be a third party plugin conflict impacting Site Kit in your case. If we can pinpoint the plugin I’m also happy to do some testing. While the issue no longer occurs in troubleshooting mode on your site it may reoccur once more if we can’t determine the cause.

In relation to the console error you reported I’ll check this with the team. Thank you for sharing! I’m unsure at this point why this may occur.

Let me know how you get on with the troubleshooting check above.

Many thanks for performing those troubleshooting checks, I’ll test the same plugin on my side for any possible conflicts.

As you didn’t encounter the same error after further checks with Regenerate Thumbnails in troubleshooting mode can you inform me if the same occurs when you exit troubleshooting mode?

I’m also wondering is there something at host level impacting Site Kit operations, given there are other failed connections to WordPress.com services evident on of the screenshots you kindly shared. Do you have any other WordPress sites setup from the same hosting platform?
