Bitcoin Forum

Yep, yet another post about this.  I have the bitcoin client, I have guiminer 2011-05-01, I have followed the instructions for solo mining.  I have disabled my AV and firewall etc just in case.  I have followed the bits and pieces on the various forums.  No matter what I have tried I simply get the "Problems communicating with bitcoin RPC" message constantly.

Does guiminer actually work at all in solo (same machine) mode?  If so can anyone tell me what steps EXACTLY I have to do to get this working?

At this point.... wondering if bitcoin mining is worth this level of annoyance.

I have the same problem as above, using win7 with GIUMiner and bitcoin on the same host, I get the 'problem communicating with bitcoin RPC' error. A/V is disabled as well as local firewall. All blocks downloaded fine.

i am pretty sure the problem is a missing line in your config file.
i bet the bitcoin client when running in server mode used to allow any connections
but somewhere along the line it was updated to block all by default.

thus my config file used to be like this that was generated by guiminer.
The file is called bitcoin.conf and resides in bitcoin's application data folder.

rpcuser=fcmatt
rpcpassword=your_password

But then I had to add this line below and it started working.

rpcallowip=all

my two cents. i might as well try this old line out. if this was helpful feel free to

(i have as of yet to have a single bit coin or fraction of it. too bad that bitcoin faucet
seems empty or offline now days.)

I get this same error too when trying to solo mine. I can pool mine no problem. Checked my config file and its all good. Got me beat atm.

I had to go back to BitCoin v 0.3.21 to not get the RPC connection problem  :-\

Yea but I thought they fixed that??
