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:
Expected Result: 200
Current Result: 500 Internal Server Error on CloudFlare server (see screenshots)
Only bots/tools/services are blocked. Regular users can still use the website.
If you disable CloudFlare (bypassing CloudFlare), everything works fine.
I already tried to debug with my hosting provider, but after several tries, we can see that the problem comes from CloudFlare itself, but not from our server.
For test purposes, we even installed a fresh version of the website with default configs.
- I don’t have any Firewall rules, only default settings.
- CloudFlare bot protection is turned off, but even in this case, it should show a kind of 403 restricted error, but not a 500.
- DNS settings and SSL settings seem to be OK. However, the error persists.
Please help us, since many services that we’re using are blocked now: Pinterest, Publer, etc. They can’t access the website, read our RSS, etc.
I will be very appreciative of any help.
I really appreciate any help you can provide.
PS. I submitted a support ticket, according to the advice on their 500 error troubleshooting guide, because the issue comes from CloudFlare, and not from our server, but it seems that the CloudFlare team is quite busy at the moment…
