Security WAF Rule to block requests that doesnt match full uri

I have the following rule on cloudflare Security WAF:

(http.request.full_uri ne "http://tunnel.xxx.com" and http.request.full_uri ne "https://tunnel.xxx.com")

(http.request.full_uri ne "http://tunnel.xxx.com" and http.request.full_uri ne "https://tunnel.xxx.com")

I also tried:

(http.request.full_uri ne "tunnel.xxx.com")

(http.request.full_uri ne "tunnel.xxx.com")

Checking the logs at Security > Events it doesnt show the full uri, just Host "tunnel.xxx.com" Path "/" It should block any request that is not any of these uri Im testing the rule with the following example request:

$headers = @{
    "X-Large-Header" = "A" * 1
    "User-Agent" = "WebSocket++/0.8.2"
    "Upgrade" = "websocket"
    "Connection" = "Upgrade"
    "Sec-WebSocket-Key" = "dGhlIHNhbXBsZSBub25jZQ=="
    "Content-Type" = "application/octet-stream"
}

Invoke-WebRequest -Uri "http://tunnel.xxx.com" -Method Get -Headers $headers -Verbose

$headers = @{
    "X-Large-Header" = "A" * 1
    "User-Agent" = "WebSocket++/0.8.2"
    "Upgrade" = "websocket"
    "Connection" = "Upgrade"
    "Sec-WebSocket-Key" = "dGhlIHNhbXBsZSBub25jZQ=="
    "Content-Type" = "application/octet-stream"
}

Invoke-WebRequest -Uri "http://tunnel.xxx.com" -Method Get -Headers $headers -Verbose

The rule is blocking the request, why? I only have that rule active nothing else, turning it off the request succeeds, maybe at the WAF side the full uri is different? How i could debug this issue?

Security WAF rules doesnt work for Cloudflare tunnels?

I have created some rules at DOMAIN > Security > Security rules For example:

(http.request.method ne “GET” and not len(http.request.headers[“upgrade”]) > 0 and not len(http.request.headers[“connection”]) > 0 and all(http.request.headers[“upgrade”][] ne “websocket”) and all(http.request.headers[“connection”][] ne “upgrade”))

(http.request.method ne “GET” and not len(http.request.headers[“upgrade”]) > 0 and not len(http.request.headers[“connection”]) > 0 and all(http.request.headers[“upgrade”][] ne “websocket”) and all(http.request.headers[“connection”][] ne “upgrade”))

https://i.imgur.com/LxiRh4a.png Im testing a connection to my tunnel but the rules doesnt seen to work, for example i did a POST request and it didnt got blocked the rule was suppose to block any request thats not a GET So, these rules doesnt apply to Cloudflare tunnel?

How to use cron?

I have this test repo on deno deploy:

import express from 'express'
import { cron } from "https://deno.land/x/deno_cron/cron.ts";
const app  = express()

app.listen(3001, () => 
{ 
    console.log('\u{1F680} API running!') 
})

cron("*/60 * * * * *", () => {
  console.log('ok');
});

import express from 'express'
import { cron } from "https://deno.land/x/deno_cron/cron.ts";
const app  = express()

app.listen(3001, () => 
{ 
    console.log('\u{1F680} API running!') 
})

cron("*/60 * * * * *", () => {
  console.log('ok');
});

It does print API running but not the console log on the cron lambda, why is it not getting called?

How to know if my tunnel is getting throttled?

With 100 client connections locally on my websocket server like std::string url = "ws://localhost:8091"; (client) I calculated latency ~200ms until client receive server response But routing the same 100 connections from the cloudflared tunnel like "ws://abc.domain.com"; the latency goes 1000ms + each client connection is sending data of around ~120kb , it only send a new request when server replied Could be Cloudflare throttling it? or my network not being able to handle all data? Checking on Windows Task Manager i can see Network 68% ~280Mbps, i have an internet of "500 mega" Is it possible somehow to check if im getting throttled?
