What is the name of the domain?

my.site

What is the error number?

not entitled to use a custom response

What is the error message?

not entitled to use a custom response

What is the issue you’re encountering

Not able to activate WAF rule

What steps have you taken to resolve the issue?

Issue Summary:
I’m trying to create a WAF rule to allow only a specific IP address and block all others. The expression I’m using is:

not ip.src eq 123.123.123.123

I select the “Block” action (not custom response), but I keep getting this error:

“not entitled to use a custom response”

What I Tried:

  • Ensured no custom response was selected
  • Used both WAF Custom Rules and Firewall Rules
  • Tried in different browsers
  • Checked plan level (Free/Pro)

Still, the error persists.

Question:
Is this a known issue? Any workaround to simply allow one IP and block all others?

Thanks in advance!

What are the steps to reproduce the issue?

Simply try to add the rule, it should work on all plans but it doesn’t work on mine.

Check all existing rules for one which uses a custom response and remove / edit it.

thank you for your answer, I checked that, there is only four rules and all of them are set to block so they shouldn’t be the reason for this error. I also checked if there are any transform rules which might cause the problem but also nothing there, any other ideas for digging into this problem further?
