zero (now one) connections

[darkwon]

Hi,

I haven't changed anything in my setup hardware or software wise, usually got around 20-30 connections immediately for the past 6 weeks. But now suddenly I'm stuck at 0 connections, sometimes it will go up to 1 or 2 but then quickly drop back to 0 without downloading the latest block. I'm stuck at 136916 here.


Any ideas?

Try to add some nodes in you bitcoin.conf

eg:

addnode=biddingpound.com

http://canyouseeme.org/ check for port 8333. if you get the green light then id just reformat, but if you don't, try port forwarding or temporarily hooking your modem into your computer to see if it starts updating.

I did this, and also added another 4 fallback nodes from the wiki. After restart I had 1 connection for a second, then it jumped back to zero and stayed there. Some minutes later I again had 1 connection for 10 seconds till it jumped back to zero. Is something actively killing my conns?


I really never had any problems with connections, but now that I make a huge transaction suddenly everything goes wrong? Please help me :/




--- ctoon6: I get this when checking:

Error: I could not see your service on 91.65.xxx.xxx on port (8333)
Reason: Connection timed out

I'm using the client built-in upnp for port forwarding and never had any problems getting lots of connections (over 6) before. Also I'm on cable internet so I can't really go around the router.

[ctoon6]

something is blocking connections, software firewall?

[darkwon]

Yes, that was my first idea, too. I have a software firewall and although it never made any problems before it was the first thing I shut down to try again, didn't help.

[ctoon6]

Do you have multiple computers running on the same public ip with bitcoin.

[darkwon]

No, just one computer.

And another strange thing happened: I'm now stable at exactly 1 connection for the last 15 minutes and the client even managed to download the latest blocks. Shouldn't it now start to acquire more connections, since it's obviously not really blocked and connected to the network successfully? This all doesn't make any sense to me.

[ctoon6]

did you test the port while the peer was connected?

[darkwon]

Yes, I did the test. Port 8333 is still not open to the outside (which is correct imo, since it's only opened for the bitcoin client via upnp, right?), I am still connected to one lonely node, blocks are downloaded successfully, but no more than this one connection get opened.

[ctoon6]

do you know how to properly forward ports? you could try manually forwarding port 8333. if you need more instructions on how to do this post or look it up on portforward.com.

[darkwon]

Sure I could try that, but

1. I have 1 (one) active working connection to a node; connected through port 8333,

2. I had the router from the beginning and in over 6 weeks it never gave me problems, constantly getting 20-30 connections,

3. I use the built-in uPnP feature which always has worked flawless as a port-forwarding tool.


So this tells me the port is not the issue here, right?

[ctoon6]

But there is an issue, and from what you describe, clients can not connect, and upnp is not exactly an exact thing either.
