Re: [ANN][ROI] ROI Coin | CPU Only Solo Mining Hybrid | 15% POS

The most important thing you need to check into is that your wallet is on the exact same block as our block explorer. If you are mining blocks and those are being rejected it is very likely you are not on the active chain...

Well, I did a fresh install of the wallet.
Checked the blockchain number in the wallet, checked the blockchain number in the explorer. They were the same.
Turned on the debug in the miner, and checked it was running the correct blockchain number, the one in the wallet +1

But I still get: [2018-01-01 18:18:27] accepted: 0/1 (0.00%), 888.54 hash/s (booooo)
[2018-01-01 18:37:17] accepted: 0/1 (0.00%), 981.51 hash/s (booooo)

So I guess something else must be going on!

Hello,

When you did a fresh install, did you delete all files, except the conf and wallet.dat? If you go to the wallet, Help > Debug > Peers. Do you see any peers on a version other than 112 or 113?

If you could also send us your debug log file (dev@roi-coin.com) Please zip it as it can be a large file. It would help us get a better picture of what is going on.

Thank you for your patience. Wouldn't be New Year without a wrench in the works some where.

Could you please tell me how to get the on screen debug output to a log.txt file?

There will be a file in your wallet folder called debug.log and you can view it as a text file no problem.

Cool! Thanks I found the debug.
Here is a portion of the logfile where the block failed to create:

2018-01-01 18:33:29 ERROR: ContextualCheckBlock: block height mismatch in coinbase
2018-01-01 18:33:29 ERROR: ProcessNewBlock: AcceptBlock FAILED

Okay if you see that exact error once in a while that can be normal. This can happen when 2 miners mine the block at nearly the exact time. One miner gets to win the block and the other miner loses it. If you see this error on every mined block and block after block then this is not normal and we have a problem that needs to be looked into right away. Also you have connection issues showing up in that log. Have you checked your firewall settings to make sure everything is ok there?

Since I did a reinstallation of the wallet, and deleted all the files exept the wallet.dat and the ROICoin.conf
I have had 11 failed found blocks in about 2 hours. So yes, everything I find across those 4 mines are marked as failed, since yesterday evening
In mather of fact I havent had a single Block since yesterday evening, so for about 22 hours not a single successful block found.

I don't know what those connection errors are, but my nat, firewall and windows firewall are good to go ;-)
The miners just connect fine and since last night nothing changed on the firewall or nat config.

I am willing to provide my receiving address in an email, or other means, so you can check I was just solo mining fine.
