Http/1.1 403 forbidden when trying to access a server


I have been trying to connect a device to my local server though Cloudflare tunnel, I can access the server fine through the domain but when the device tries to connect it gets this error
"http/1.1 403 forbidden
server: Cloudflare
date: fri, 02 dec 2022 04:46:41 gmt
content-type: text/html
content-length: 151
connection: keep-alive

403 Forbidden

403 Forbidden

cloudflare "

I tried disabling cache and browser integrity check but still the same error

any thoughts ?

Check your firewall log. You can filter on Ray ID: 77316b945974dc9b

It’s empty, do I have to have a payed account to log events ?
