<p>I'm trying to run minderd with the following command (I'll replace my email address with EMAIL)</p>
<pre><code>./minerd -o http://btc.kryptex.network:7777 -u EMAIL/worker -a sha256d -R 2

<p>but getting the error &quot;HTTP request failed: empty response from server&quot; I tried to run it without http:// but same result.</p>
<p>I can ping btc.kryptex.network from the server. Also tried btc.kryptex.com.</p>
<p>What can it be?</p>
<p>Ubuntu 24.04.01 Xeon Gold 6148</p>
<p>Probably not very efficient for mining anyway I guess, but is there a better miner program to use to utilize the CPU above?</p>

You cannot mine BTC using just a CPU, it is just orders of magnitude too slow. Even if there was a pool out there that supported such slow contributors, you'd make around ~2 sats per year with a 100 MHash/s CPU (a rough guess), or 2 USD per 1000 years. You need specialized ASICs.
