**MOL4 Beta: Cloudflare Error 1010 on XC API connections (works fine in MOL3 / TiviMate / UHF)**
Hi all,
**Issue:**
MOL4 Beta fails to load content from my provider with Cloudflare Error 1010 ("banned browser signature" / Browser Integrity Check). The identical connection (same XC API credentials, same network) works perfectly on:
- MOL3 on Z11 Pro Max
- MOL3 on Z mini
- TiviMate
- UHF
It fails on:
- MOL4 Beta on Z12 Ultra
- MyTVOnline+ on iOS (identical 1010 error)
**What I've tested:**
- Changed the API User Agent to a Chrome desktop string → still 1010
- Confirmed the error occurs against two independent Cloudflare-protected endpoints, including a direct connection to the provider and connect to IPTV Editor— so seems it is not one server's firewall rule
- Switching users (IPTV Editor) changes the behavior (successful refresh) but I think that may be temporary.
**Analysis:**
Since the UA string makes no difference and only the new-generation apps (MOL4 / MOL+) are affected, the trigger appears to be the request fingerprint of the new network stack itself (TLS handshake / header set), which Cloudflare's default Browser Integrity Check is flagging. MOL3's stack passes the same check. Nothing user-configurable in the app can reach that layer.
This will affect MOL4 users on any Cloudflare-fronted backend, which is a large share of providers, so it seems worth addressing before the official release.
I can reproduce and send logs if necassary, just need to know how/where the logs are, and what you need.
Z12 Ultra, MOL4 Beta, wired Ethernet, US.
Thanks!
