Title: Blocks rejected when solo mining but accepted on pool? Post by: Hamukione on February 18, 2020, 10:40:50 PM Hi Bitcointalk.
So, I got my hands on a good old Butterfly Labs Jalapeņo. It runs at around 8GH/s and its enough to play around with some old dead coins and mine for fun. I found a coin that I have mined for a few days and today the network hash dropped to a point where it should be easy for me to solo mine it. So I switched over and started to solo mine, and I did start mining blocks.. But every single one of them got rejected. This makes no sense to me since Pool mining was working great. Could it be a problem with my network? Do I need to port forward the wallet rpc port? Miner issue? (Using cgminer). Any ideas? Title: Re: Blocks rejected when solo mining but accepted on pool? Post by: JayDDee on February 18, 2020, 11:58:25 PM If you're submitting blocks and they are being rejected it's not problem with your network.
More "technical" details would help, like command line options and console output. The backstory wasn't necessary. Title: Re: Blocks rejected when solo mining but accepted on pool? Post by: NeuroticFish on February 19, 2020, 07:18:12 AM Did you set the conf file correctly? Afaik you have to do a little more than just start the wallet/daemon.
I don't know if this is (still) OK for the coin you mine, since it's 5 years old, but it could be a start: https://bitcointalk.org/index.php?topic=521563.0 At least the Code: server=1 Title: Re: Blocks rejected when solo mining but accepted on pool?

I am currently at work, but when I get home tonight I will check the config and see if I forgot to add this. Ill report back later with my findings! :D Title: Re: Blocks rejected when solo mining but accepted on pool?

I changed it and its now: rpcuser=x rpcpassword=x rpcallowip=127.0.0.1 rpcport=18124 server=1 daemon=1 listen=1 Still getting rejects :/ Title: Re: Blocks rejected when solo mining but accepted on pool?

Perhaps you should provide more info as I requested rather than following random advice based on incomplete information. Title: Re: Blocks rejected when solo mining but accepted on pool?

Gotcha, ill setup the solo mining again tonight and take some screenshots and a copy of the config. Title: Re: Blocks rejected when solo mining but accepted on pool? Post by: JayDDee on February 20, 2020, 04:49:33 PM Based on your initial problem description I suspect a SW bug in the miner for solo mining. The protocol
sems to be correct if you're getting blocks, submitting hash and getting a reply. The reject reason will provide more info. Invalid shares are usually user error (wrong algo) or a SW bug in the hash code. There are other types of rejects that could point in another direction. You could try another version of cgminer. I've never used it myself so I'm not familiar with it's issues and quirks. But it's best to get more info before drawing any conclusions.

I am not sure how to compile it on Linux, but I have a server that I could test it on instead. And I dont know how to compile previous versions of CGminer on Windows.

Got a screenshot for ya: https://gyazo.com/53f7ab86c0f2bdff9d8f8f299d4c23f0.jpeg That is what I get when I hit a block. Title: Re: Blocks rejected when solo mining but accepted on pool? Post by: JayDDee on February 22, 2020, 11:15:54 PM Thanks but unfortunately it doesn't display the reject reason. It seems there is a software bug
that only affects solo mining. Your best bet is to look for another compatible miner, I can't help you there. Title: Re: Blocks rejected when solo mining but accepted on pool?
