Cloudflare issue

gombodorj | Last updated: Sep 23, 2024 07:23AM UTC

I am having an issue when proxying traffic between a mobile app and a back-end server that is behind Cloudflare. The error is: 'The client failed to negotiate a TLS connection to x.x.x.x:8080: Remote host terminated the handshake.

Are you able to connect to other HTTPS sites using a browser from your mobile device? Does the mobile app you are testing do certificate pinning?
