Issue with routing traffic through a server.
Issue with routing traffic through a server.
What browser are you browsing with? Are there any updates available for your router's firmware?
It might be related to your web browser or the router's firmware being outdated. You could switch to another browser or update the router settings. Comcast (Xfinity) has previously interacted with BitTorrent, though I'm not suggesting they're doing anything harmful—it wouldn't be unexpected if they were.
I use Chrome with the latest updates. I rely on QBittorrent and it previously seeded to my tracker. Now it still does when I download files from streaming services like TV or movies. However, I need to re-seed back to maintain my ratio. The stats from the tracker are listed above. I'm attempting to open a port to seed again, but it's not working since my router blocks it.
If it allows you to link and your client confirms peers are linked, it seems unlikely a router port problem is the cause—though I might be mistaken. Consider switching to edge or using Internet Explorer to reach the router web interface. It could be that Chrome isn’t compatible for this task. Apps and games > port range forwarding likely points to the correct screen you need.
Sounds like a bug in the firmware. It does happen. You can look in to 3rd party firmware, which could potentially fix the issue. But not all routers support that. Just make sure you read the documentation before trying to flash 3rd party firmware otherwise you might be buying a new router.
