Title: bitcoin client not connecting
Post by: trout on April 28, 2011, 08:11:28 PM
Hi,

the bitcoin client I'm using often can't connect to the network.
It shows "0 connections" for like an hour. THen sometimes it goes to 1 and then back to 0.

Sometimes closing it and starting again solves the problem, sometimes not.
Also, often it just works fine  - finds several connections immediatetly

anybody has a similar problem?

my network connection is pretty good.

Need more info.  Are you behind a firewall?  What OS are you using?

Could your ISP be traffic shaping?

traffic shaping against bitcoin? not very likely, especially
given that it's very tolerant to torrents..

sorry I realized this should have been posted in the "technical support" board, rather than "bitcoin discussion" :/

Could your virus software or Windows security settings be interfering?

In both your cases, did you login to your router and setup port forwarding from the internet to the internal LAN IP of your PC with bitcoin?  From the noob guides I read it said that it's not required, however, after I installed bitcoin on win7 I was stuck at 0 connections for a while.  As soon as I setup port forwarding / tcp / 8333 to the internal IP I saw a dozen connection come in at once.

Hope this helps someone.
