Handling Login Attacks

Hello everyone, looking for some help related to identifying attacks to certain pages esp. login pages I already setup verified bots, page limits etc which gets revoked. However certain attacks are targeted and the attack originates from multi cloud and the attacker program swaps to new ip when existing one gets blocked. How can I identify the attacks? Currently we are using JA3 and JA4 fingerprint to spot but thats very manual and tedious process . How can I make use of openly available JA4 database to spot the outliers easily? Or infact any other way?...

Trying to add R2 but it just seems to be looping

Hey, I'm trying to readd R2 to my account and it just seems to be looping and not actually adding to my account as it was "previously removed" I can't see any outstanding fees or anything on the acc and it just seems to not actually add it, any assistance would be great.

Is it possible to get the old DNS records from a domain that got classed as moved off Cloudflare?

Hey everyone, Wondering whether its possible to get the DNS records from a domain that expired on another registrar (Sav - P.S hate those guys). It got classed as moved off Cloudflare and has now disappeared from dashboard as it took 3 weeks for me to get the domain back from Sav. So I don't have to go through and set everything up again, just wondering whether theres a way to get those old records and restore them?...

Cloudflare Phishing page bug

I have a domain that has a Phishing page report, which I already sent for review, however, the Cloudflare phishing page has a bug, some user(s) see a Turnstile Captcha, which can be completed, but when you click Ignore & Proceed, it returns you to the same page, without any turnstile captcha, if you click the button again, it gives you a Cloudflare error that the turnstile token is missing.

Help with Pro Plan

Hello! I'm super new to Cloudflare: last week I paid for a pro plan with a domain that I ended up deleting (huge newbie mistake), and now am hoping to transfer that plan to a new domain that I have set up. Does anyone know who I should contact/what I can do? I tried to contact billing@cloudflare.com but they don't accept emails anymore. Some help would be super appreciated! 😣

Cloudflare Stream Issue

Trying to understand how Cloudflare says our company has streamed for 2 million minutes and charged us without an invoice. The streams we’ve done do not add up to this.

How can I proof check who blocks access?

According to https://blog.cloudflare.com/russian-internet-users-are-unable-to-access-the-open-internet/ Russian providers block traffic from Cloudflare. Is there a way to proof check this? What commands can I run locally to see that traffic is blocked by providers and not Cloudflare itself for example?...

Unexpected SSL Certificate Behavior and Switching Between Certificates Without Change

I'm experiencing a strange issue with my domain. The Cloudflare proxy is currently disabled, and the SSL/TLS setting is configured to Full (strict). However, I’m encountering the following behavior: - When the proxy is enabled, visitors receive an invalid SSL certificate, which does not match the domain or expected Let’s Encrypt cert. - When the proxy is disabled, the correct Let’s Encrypt certificate appears intermittently, but sometimes a Cloudflare-branded certificate is presented instead....

Video transforms on CF Stream - can Cloudflare combine videos?

I'd like to stitch 2 videos together. I see here you can transform videos, does this include stitching them? If not, how can I achieve this?

Media transformations: Dynamically optimize and transform images and video on-the-fly, regardless of where they are stored

Connect to tunnels from worker.

I see that it is possible to run a tunnel and then connect to hyperdrive through the tunnel on my worker. I wanted to know if its possible to access other tcp applications running through tunnels? I have both a mysql server and a redis server running on my server and I want to be able to use cloudflare tunnels to access them from my worker. I can access mysql using hyperdrive but I don't see a way I can access redis. Here is the link to the docs of connecting to hyperdrive from a worker over tunnels if that helps...
