 You need to disable or bypass "Browser Integrity Check" in Cloudflare Dashboard via one of these methods:
 - (Easiest) Add your Uptime Kuma host IP address to [IP Access rules](https://developers.cloudflare.com/waf/tools/ip-access-rules/) as an Allowed address, optionally across every domain in your Cloudflare account
-- Allow Uptime Kuma to [bypass the check via WAF Custom Rules](https://developers.cloudflare.com/waf/custom-rules/skip/), only applies to one domain at a time
+- Allow Uptime Kuma to [bypass the check via WAF Custom Rules](https://developers.cloudflare.com/waf/custom-rules/skip/), and special header. E.g. lets add to the Kuma request header (please replace `kuma-qwerty123456` with your own random value):
+   ```json
+   {
+   "kumaping":"kuma-qwerty123456"
+   }
+   ```
+   Now create a rule where you will bypass JS challenge if header is presented. You can also add multiple domains after `or` E.g.
+   ```
+   (http.host eq "domain1" and all(http.request.headers["kumaping"][*] ne "kuma-qwerty123456")) or (http.host eq "domain2" and all(http.request.headers["kumaping"][*] ne "qwerty123456"))
+   ```
+   and at the end of the rule JS challenge. Now challenge will be only triggered if `kumaping` header is not presented or it has a wrong value.
 - Use a [Configuration Rule](https://developers.cloudflare.com/rules/configuration-rules/) to disable the check for your Uptime Kuma IP address
