Cloudflare CDN for Siteground Preventing Pinterest from Pulling Meta-Data

[kwkowalski]

Hello,

Hoping someone could shed some light here.

I’m trying to enable Rich Pins for Pinterest and to do so they have you submit one of your blog article’s URLs to make sure they can read the meta-data. The problem is, every time I try to get it validated, it returns a 500 error, unable to access the server.

After checking the logs on Siteground and testing a few more standard things, I found this thread on here that has the same issue:

A 500 Error on the CloudFlare side for all external services/tools/bots

Hello, I’m experiencing a kind of 500 Error on the CloudFlare side (not my server) for almost all possible bots/services/tools. The website is - https://www.difference101.com/ Users can still access the website, and the curl command is working fine. But W3C Validator, Pinterest, Redirect Checker, Redbot checker all have issues with the same error (500 on the CloudFlare side) To test, please visit any of the following services: https://redbot.org/?uri=https%3A%2F%2Fwww.difference101.com ht…

After running my same URL through Redbot.org, I receive the following:

HTTP/1.1 500 Internal Server Error
Date: Wed, 10 Feb 2021 19:46:18 GMT
Content-Type: text/html; charset=UTF-8

CF-RAY: 61f855e03990214b-SJC
Server: cloudflare

If I deactivate my Cloudflare CDN on Siteground and test validating my URL on Pinterest again, it goes through successfully.

I do have a ‘sg_worker’ if that makes any difference. I saw it mentioned in the linked discussion.

I’d like to know if there is a way to fix this so I don’t have to deactivate my Cloudflare?

Thank you very much!

Kind Regards,
Kraig

Hello Kraig,

I see that you linked my topic here, so I’ll try to clarify a little bit about a possible solution for this issue.

You don’t need to deactivate the whole CloudFlare integration, but rather only a Cloudflare Full Page Caching feature inside the SG Optimizer plugin from Siteground. At the moment, it’s the only available solution that I know till they didn’t fix their worker integration with CloudFlare.

Please check out my detailed answer on how to do it inside this thread, and don’t forget to create a support ticket and send them the links to this and similar issues that their customers have with the Cloudflare Full Page Caching feature.

Regards,
Alex

I will let you know their response here as soon as they answer. UPDATE 1 - Possible Temporary SOLUTION: In my case (on my website - Difference101.com), the issue was related to the Cloudflare Full Page Caching functionality inside their SG Optimizer plugin. When you enable this feature, Siteground creates a worker inside your CloudFlare. And as we know, this worker causes many issues. I asked Siteground to keep my ticket open till they fix it, and at the moment, it remains open. The solution…

Hi Alex,

Thanks so much for reaching out! I’ll definitely give that a try and read through the thread that you linked.

Also, I immediately opened a ticket after opening this thread, to get more eyes on it. Hopefully, they can start working on a fix.

Thanks again!

Kind Regards,
Kraig
