“john_doe” is a dynamic parameter, the next URL can contain “jane_doe” and so forth. I am only looking to replace “im_team” with “members” but also recognize the URL may contain at the end dynamic values.
May I ask if you are trying to access with or without www when you test this?
Is A www existing and proxied and at the DNS tab of Cloudflare dashboard for your domain name?
If you are trying to follow the path from /imt_team/some-user/ to be /members/some-user/, use $1 instead of wildcard * (apex) at the end of the https://www.testsite.com/members/*, so would be https://www.testsite.com/members/$1.
