How to set rule to exclude cache for specific resource?

Hello,

We are using Wordops(https://wordops.net/) to install wordpress site.

There will be management Wordops Dashboard, and it will look like this screenshot: https://prnt.sc/5ihNLSv_VB93 by access the URL https://mysite.com:22222

Port:22222 is specifically used for the above purpose, and it need a username and password to access. You may check the document at https://docs.wordops.net/commands/secure/ for more details if you like.

But, after migrating the domain onto Cloudflare, the issue is that when accessing the whole site, it will ask ask for password Authorization, and please check the screenshot: https://prnt.sc/2vWnjdrlNON0

Obviously, it seems that Cloudflare cache the page at https://mysite.com:22222, and cause whole site access need authorization.

So, anyway to resolve the problem please?

Thanks
