<p>I've created a litecoin-qt server with the following configuration:</p>

<pre><code>{
"pools" : [
        {
                "url" : "http://192.168.10.5:9332",
                "user" : "something",
                "pass" : "somethingelse"
        }
]
,
"auto-fan" : true,
"temp-cutoff" : "95",
"temp-overheat" : "85", 
"scrypt" : true
}
</code></pre>

<p>I'm able to connect to it from at least 3 different machines on the network, plus one connection from itself (I'm having cgminer run on the server).</p>

<p>However, I'm unable to connect from any other machines - it flashes the following:</p>

<pre><code>[2014-02-04 21:47:03] Pool: 0  URL: http://192.168.10.5:9332  User: something Password: somethingelse

Are those other machines outside of your network and getting blocked by a firewall or port rules?

Hi Jacob - no, they're all on the same wifi and the other machines can ping the .10.5 one. This is all on Windows - am I running into a connection limitation?

Bitcoind by default accepts up to 8 connections. Have you tried pinging the ip address from the trouble computers?

Yup - did that again before typing the above - am able to receive responses. Still seeing the above message (second quoted block) - note, this isn't a stratum pool.

It may be a network issue most likely. Are you using the correct ip address, port, and password for sure? The following line suggests that no communication is even established, so it's not a problem with configuration of pool. `HTTP request failed: Operation timed out after 60000 milliseconds with 0 out of -1 bytes received`

Yeah - I'm using the correct IP - using the same config on the other machines. Two of the worker machines are using cudaminer, 1 is using cgminer (with the config exactly as the first quoted block). The server machine itself has it modified to use 127.0.0.1 as the IP address, no other change.

# Unable to connect to litecoin-qt server from more than 3-4 machines

(Asked by: username_0 on 2014-02-04)

I've created a litecoin-qt server with the following configuration:
{
"pools" : [
        {
                "url" : "http://192.168.10.5:9332",
                "user" : "something",
                "pass" : "somethingelse"
        }
]
,
"auto-fan" : true,
"temp-cutoff" : "95",
"temp-overheat" : "85", 
"scrypt" : true
}

I'm able to connect to it from at least 3 different machines on the network, plus one connection from itself (I'm having cgminer run on the server).
However, I'm unable to connect from any other machines - it flashes the following:
[2014-02-04 21:47:03] Pool: 0  URL: http://192.168.10.5:9332  User: something Password: somethingelse

And ends with:
 [2014-02-04 21:40:48] Timed out waiting for data on socket_full
 [2014-02-04 21:40:48] Initiate stratum failed

The datetimes are slightly off since I fetched these logs in different run instances.
