brillo2000 Posted September 11, 2018 Share Posted September 11, 2018 HI there I have used bitcomet for years and its always been brilliant once I have got my listen port up and running. recently though the green light turned yellow and today it is now grey. I have followed all the instructions on the forum, turned off the firewalls on my pc and my modem. Set up a personal listen port on the modem and matched it to the listen port on bitcomet but it still won't connect. What can I do to try fix this? any help would be greatly appreciated Thanks Link to comment Share on other sites More sharing options...
Rhubarb Posted September 12, 2018 Share Posted September 12, 2018 Try a complete reboot first: power down BOTH computer and modem/router, wait at least two minutes, restart the modem/router and, when it 'locks', restart the computer. You could also try a 'high' num,ber for the port (your ISP may be blocking lower port numbers). I set mine to around 14,000 If that still doesn't work, try a fresh installation.

brillo2000 Posted September 12, 2018 Author Share Posted September 12, 2018 Brilliant, It seems to have worked. The old turning it off and on again trick! I should have known, I've watched enough I.T Crowd!! Thanks again Link to comment Share on other sites More sharing options...
whitetiger1668 Posted September 28, 2018 Share Posted September 28, 2018 i having this problem too. but when i started to download, the light became green. but before update, it's works normal as green keep light on. Link to comment Share on other sites More sharing options...
george2018 Posted September 28, 2018 Share Posted September 28, 2018 i have same problem, after download starts ports are green, build 1.51 Link to comment Share on other sites More sharing options...
Rhubarb Posted September 28, 2018 Share Posted September 28, 2018 If the ports are green that means they're open. It may take a moment to happen as the program runs a check but green = working Link to comment Share on other sites More sharing options...
george2018 Posted September 29, 2018 Share Posted September 29, 2018 (edited) no they have green color only after some high speed download starts, if there's no download it stays gray: it's same on 1.52 as well, disabling KIS 2019 protection doesn't help, i have ZTE F660 router with correct port forwarding, if you enable DHT network then only udp port is opened, as for tcp port it needs some torrent download to open, maybe windows 10 17134 latest updates changed something, i haven't checked with much older versions, but i think they behave in same way, i installed 1.20 build now and nothing changed, when i start some download it's working again: here's my settings: i think it's windows update that changed something, or my router is broken, it could be internet provider as well, when i install 1809 rtm build in october i will check again, i'm using bitcomet since early 2000 so i have correct settings and never had problems before on those settings i also opened all ports in router: firewall is off in router, as well as windows 10 firewall, only using KIS 2019, as long as it keeps opening itself after download starting it'll do fine, it behaves same way if i enable upnp port mapping and dmz host in router Edited September 29, 2018 by george2018 (see edit history) Link to comment Share on other sites More sharing options...

george2018 Posted October 1, 2018 Share Posted October 1, 2018 (edited) with ZTE F660 router when you enable DHT network only UDP port opens, with TCP port you have to port forward in router settings, maybe it's new windows 10 update, because i also installed very old bitcomet versions and nothing changed, C:\Windows\System32\drivers\etc there's nothing wrong with hosts file, so it's either windows update or internet provider changed something, i will check on freshly installed 1809 windows version later, i never had this problem before using same settings, it needs around 1-2 minutes download time in order to open port, without downloading something it's always stay gray with Port detection failed error, i checked another computer on same router with windows 1709 build using latest update and it has same problem, port only opens when there's some download going Edited October 1, 2018 by george2018 (see edit history) Link to comment Share on other sites More sharing options...

Turning off your firewall and/or your antivirus is a really, really bad idea (it lets all sorts of "nasties" wriggle through to your computer). Said programs are there for a reason, not just for mere decoration, so it's best that you learn what their purpose is and why they're there.

Rhubarb Posted October 2, 2018 Share Posted October 2, 2018 Some people are reporting that the problem lies with IPv6 - disabling that seems to make things work again. This could be an ISP problem (that IPv6 hasn't been implemented). Try disabling it in preferences Link to comment Share on other sites More sharing options...
george2018 Posted October 2, 2018 Share Posted October 2, 2018 (edited) or provider changed something, when download starts it's fine again after 1-2 minutes download (with proper port forwarding in router), most ports seems closed when i check https://portchecker.co but when i start bitcomet 65000 port is open, but after exiting bitcomet port is closed again, so something is preventing it to stay open all the time even with port forwarding, i never had this problem before, i don't do any online gaming, but browsing is working fine, as well as torrents, so it's only minor problem Edited October 2, 2018 by george2018 (see edit history) Link to comment Share on other sites More sharing options...

On 10/3/2018 at 12:09 AM, george2018 said: after exiting bitcomet port is closed again Once BitComet is closed, no other program is allowed to use that specific port and, since BitComet doesn't need it anymore (you just closed the program), it will close, as it should. Both behaviours are working properly. Link to comment Share on other sites More sharing options...
george2018 Posted October 18, 2018 Share Posted October 18, 2018 well when i turned on bitcomet 1.51 today green light returned again, i haven't changed anything, you don't need to download anything port opens without downloading now, yesterday i update java runtime, but maybe internet provider changed some settings, well problem started after i installed 1.52 build, before that i never had any problems and port always stayed green Link to comment Share on other sites More sharing options...

Incogneetoh Posted June 22, 2021 Share Posted June 22, 2021 If I disable my firewalls and the listening port is still blocked, would it be proof that it is the router or provider (I am in a hotel) blocking the port? If that is the case, is there any way to use a VPN (I use cloudfare) to get around this issue? Link to comment Share on other sites More sharing options...
Rhubarb Posted June 22, 2021 Share Posted June 22, 2021 You would need to know what ports are open on the router and also have one opened for your intranet IP address (the VPN isn't an issue here) Basically, there is no way you can operate without actually changing the settings on the hotel router - and I don't think they would permit that And, please do not attach a 'me too' post especially when the original problem is totally different (and was 3 years ago) Link to comment Share on other sites More sharing options...
