Website, Application, Performance
1

What is the name of the domain?

add.life and many others

What is the error number?

530

What is the error message?

No message returned, just an empty response

What is the issue you’re encountering

User receiving intermittent 530 errors

What steps have you taken to resolve the issue?

I have tried across multiple browsers on multiple machines in multiple countries.

Random requests are receiving 530 errors from the browser.

What are the steps to reproduce the issue?

Try to access the sites, the CMS backoffice is more affected than the front end.

I am able to stop the error by adding the client IP address to the WAF bypass rules, which points to the issue being related to the WAF service
The sites are also not affected when accessed directly on the servers or bypassing Cloudflare altogether.

I have been able to resolve the issue on our Pro plans.

I had to deploy and migrate to the new WAF rules, and then the issue went away.

Hey Aaron, can you explain what you did? I am seeing intermittent 530s today across my domains. Thank you!
