Cpuminer problem: empty reply from server

2

When I run the following command:

minerd.exe -o http://eu-stratum.btcguild.com:3333 -u username_1 -p password -a sha256d -R 2

I get this:

2 miner threads started, using 'sha256d' algorithm.
Binding thread 0 to cpu 0
Binding thread 1 to cpu 1
HTTP request failed: Empty reply from server
json_rpc_call failed, retry after 2 seconds

How can I solve this problem?

The miner you are using does not support the stratum protocol. Instead you must use a pool that uses the old and now obsolete getwork protocol

If I see it correctly BTCGuild still offers the getwork access with the following URL:

minerd.exe -o http://btcguild.com:8332 -u username_1 -p password -a sha256d -R 2

Thanks, it's working now. I'm new to bitcoin, didn't know anything about protocols. I was just curious, but my CPU only can produce 7MH/s, and as I know that's not much. – tamas.pflanzner – 2013-08-29T09:33:39.487

Unfortunately, BTCGuild is closing down. – Vassilis Papanikolaou – 2015-09-23T23:00:31.657
