can't connect to any tracker at all

Recommended Posts

it just happen all of sudden, all ongoing torrents got problem connecting to trackers

all shows "tracker status: connection closed by peer"

I've check everything possible, shutdown firewalls, antivirus, port forward

downloading works fine before this

is this some new ISP trick for bandwidth shaping??

edit:the status shown at status bar below is green, btw, network is working fine, just tracker problems, i tried big non-pirate site like open office, ubuntu iso torrent at their official sites, it's still the same, tracker connection seems to be having problems

any ideas?

Your half-open connection limit in µTorrent may be set too high...though I doubt that'd cause the problem when µTorrent is first launched unless you always have too many torrents active at once.

The more likely explaination is your ISP is blocking somehow. What is your ISP? Done any GOOGLE searches for others with similar problems?

the half open connection limit was set to the default value 8

I tried that possibility before, removed all active torrent, completely remove old settings, reinstall, try only one torrent at a time, download from some big and official linux iso tracker, it's still the same

that's why i'm suspecting it's the ISP, i googled for it but nothing was avail, has any one recently got this similar problem here?

Still being able to download doesn't necessarily mean green either, though. Chances are, on university connections, you won't be able to forward a port. In the case of being unable to connect to trackers, Protocol Encryption won't help, as it's only for peer-to-peer connections, not for tracker connections.

thanks for the advice, i'm currently using that, the icon on the bottom is still green, thanks to DHT

but without the connections to tracker, the peer numbers diminished a lot, and the speed suffers

another problem is that there are some sites that calculate your download and upload ratio through tracker connection

without that, the ratio rate will suffer and sooner or later, i can't download anymore

about that, i tried checking the port forwarding with the port testing provided with utorrent (http://www.utorrent.com/testport.php) and some others site i found through google, it works fine, and shows that port connection are open and accepting connections

is there something that i missed here? eg. different port are used for tracker connections etc.

in our campus network, each dorm room resident has their own static ip address, which is open, and you can even set up your own web server or whatever with it.

i checked whether the port was open or not with the utorrent website as i mentioned above, as well as some other net security site that probe for open port, they are working fine, it's open connection

maybe there's a school firewall out there before it connects outside, and the firewall or router do NAT translation for other services like webserver port 80 and blocks those unnecessary one like bittorrent tracker, just my guess, anyone can confirm this?

I too have just recently had problems connecting. At first I thought it was a busy server, but it has gone on for days now. I disconnected my wireless router and connected directly with my home satellite modem with no change in status. It does not seem to login, the only error message I can find is unable to map UPnP port. I have not been using this utility long, so I am not sure where to look. My firewall settings have not changed, and I have not added any new software. I have another program that I use and I have no issues connecting there. Any ideas anyone?

tenshi said: "I have another program that I use and I have no issues connecting there."

eh?

Does this other program happen to be a BitTorrent client?

And it has no problems connecting to the same trackers?

If so, it supports my "JFK assassin on the grassy knoll theory" that those trackers are UDP-only trackers that µTorrent does not support.

I'm having the same problem out of the blue.

Everything was working great then ALL public and private tracker stopped connecting. Nothing has been updated , installed , or changed. I've tried with and without firewalls. The port always tests open and accepting connections.

I thought I might be getting filtered by my ISP but can connect to those same trackers with Azureus no problem.

All settings are default and it had been working fine until now.

I noticed others are having this problem and I'm wondering what has caused it and if anyone has found a fix. ?
