Diablo Miner: URI can't be null.

[jjustinn]

This is the error I've been getting with DiabloMiner. I'm new to the boards and am having trouble finding an answer. Thanks in advance for any help.

Paste the whole command line; all the arguments you started DiabloMiner with.

Opened the App and this is what follows.

Look at the following lines:

Server host name or IP address [[https:api.bitcoin.cz]]:
...
[2/15/12 5:53:55 PM] Connecting to: http://[https:api.bitcoin.cz]:8332/

The address you specified is garbled: [https:api.bitcoin.cz].
As a result, DiabloMiner thinks you omitted the protocol part (http://) and appends it in front of your the hostname resulting in something as nonsensical as http://[https:api.bitcoin.cz]:8332/

You are not supposed to use square brackets when typing in the hostname, just enter http://api.bitcoin.cz
No brackets, no quotation marks.
The same goes for port number; it's 8332.


Please note that you can also provide the address and logon credentials passing them as parameters to DiabloMiner:

Code:

justin-xxx-macbook-pro:~ Justin$ /Applications/DiabloMiner.app/Contents/MacOS/DiabloMiner-exe -u justin.xxx -p silvermac -o https:api.bitcoin.cz -r 8332

-u as in user,   -p as in password,   -o as in pool,   -r as in port
This is usually the preferred way of launching any miner.

It'll give me mhash updates but it keeps cycling through the error message. Also, I'm not sure what Diablo is supposed to look like when it's running smoothly, only use RPC.


Thanks for your help so far.

Got it going. Thanks dude.
