Can't connect to RPC on php server

[ozergul]

Hello guys.
I am using php to connect RPC server. In localhost, everything works fine. I moved my files to host to test and I realised that $geth->Method_Name() is not working.

If I print_r($geth), here is the result.

GethApi Object ( [_options:protected] => Array ( [version] => 2.0 [host] => 165.227.103.219 [port] => 8545 [assoc] => 1 ) [_address:protected] => http://165.227.103.219:8545 [_id:protected] => 0 )

But if I wanna get block number with $geth->eth_blockNumber() here is the result in localhost:

4495121

But in php server:

Fatal error: Uncaught exception 'RuntimeException' with message 'Failed to connect to 165.227.103.219 port 8545: Connection refused' in /home/crypuekb/public_html/GethApi.php:86

  | Stack trace:

  | #4 {main}
  | thrown in /home/crypuekb/public_html/GethApi.php on line 86

Here is the line 86:

throw new \RuntimeException(curl_error($curl), curl_errno($curl));

I am using this command to start geth server:

geth --rpcapi "web3,eth,personal"  --rpc --rpcaddr "0.0.0.0" --rpccorsdomain "*" --light

As I said, everything works perfect on localhost.. Also my php server and ethereum server is based on different hosts. And I tried my php codes at three different hosts.

Connection refused means you have a firewall blocking the port. Check your router and/or OS.

A couple of things to check:

• Check that it's indeed listening where you want it to: netstat --nlp should show you geth listening at 0.0.0.0 port 8545.
• Check that there's no local firewall, sudo iptables -L
• If there's nothing on the machine that blocks it, the problem is somewhere between the server and the client, e.g. some external firewall.

A note, though; it's not safe to expose the personal api if there are any accounts with ether on them on the - in fact, I'd recommend not to expose the node API to the internet at all if it holds funds.

I'm closing this bug since it does not appear to be a bug in geth.
