My MAG portal loads the channel list perfectly. I can see all categories and channels. But clicking any channel results in a "no signal" or black screen after 3-5 seconds. Tried multiple channels and categories. Sharing the fix.
 
This specific pattern — portal loads, channels fail — rules out portal URL and authentication issues. The problem is at the stream delivery layer.
 
This almost always means the stream server is different from the portal server. The portal authenticated you but the streams come from a CDN that your device cannot reach.
 
Yes. Some ISPs block streaming content specifically without blocking the portal/authentication. Test with a VPN on a separate device — if streams work through VPN but not directly, ISP blocking is confirmed.
 
I had this exact issue. My ISP was transparently proxying HTTP traffic which broke the stream protocol. VPN bypass confirmed it. Switched to a different DNS resolver which helped somewhat.
 
Changing DNS from ISP default to 1.1.1.1 (Cloudflare) solved the no-signal issue for me without needing a VPN. The ISP DNS was redirecting certain stream hostnames.
 
Settings → Network → Manual DNS Configuration → set Primary DNS to 1.1.1.1 and Secondary to 1.0.0.1. Restart the device after changing.
 
Another possible cause: stream timeout. If the MAG tries to connect to the stream and the response takes more than 5 seconds, it shows no signal. Slow stream server response can cause this.
 
Contact your provider and ask if they have a different stream server URL or region setting. Some providers have multiple CDNs and you may need a different endpoint.
 
RESOLVED: Provider support confirmed a regional CDN issue on their end. They gave me an alternative portal URL that routes through a different CDN. Working perfectly now.
 
Moderator: this type of issue is worth documenting. If you find the root cause, please update your thread with the specific fix so others can benefit.
