Title: No Block Source Available Error-Bitcoin Core--Help Please!!! Post by: Tech-Challenged on May 28, 2015, 02:01:05 AM I clicked on the Bitcoin Core symbol on my desktop computer to open it and I got an error. I think it said something about application failure and asked if I wanted to ignore it so I said yes (was that the wrong answer?). Then Bitcoin Core came up but now says "No block source Available" and shows zero Bitcoin in my wallet. It loaded almost instantly but says 6 years and 20 weeks behind. It shows former transactions in a grayed out box as well as previous wallet addresses I've used. I've tried to start over by downloading Bitcoin Core again, but the same thing keeps coming up..."No Block Source Available."
Can anyone help me with this? At a loss. Thank you!!! Title: Re: No Block Source Available Error-Bitcoin Core--Help Please!!! Post by: Amph on May 28, 2015, 06:03:34 AM what version is this?
that 6 years and 20 week is just the synching process, you should let it finish first, it will take a while there isn't any problem here just a incorrect understanding of how the client work Title: Re: No Block Source Available Error-Bitcoin Core--Help Please!!!

Post by: CIYAM on May 29, 2015, 04:42:55 AM Both of you are wrong. Firewalls (at least some of them) can be configured to block "outgoing port requests" so you might not want to just jump in and call people "wrong" (and if the OP is able to access internet but Bitcoin Core cannot find any peers then this could well be the reason why). In a home internet situation outgoing port 8333 requests being blocked would seem very unlikely though. One suggestion that immediately comes to mind is to try using a different internet connection (preferable via another ISP) such as a 3G one and see if that makes a difference (i.e. it could be possible that the ISP is blocking the port). |
