JSON config parse error(offset 1782)

I am getting this error
JSON config parse error(offset 1782): Invalid escape character in string.

ANd i have found it occurs mainly when i use pool settings


  • i have got two aorus 1080ti extreme addition on my mack they are giving around 1.8 k hs on default pool but i want to use em for nanopool

  • coz from last 3 hours moneropool aint showing any progress just hashes so i am skeptical about this pool . will see what it shows after 3 hours but if balance is zero i aint using it

  • This means there's an error with the 1782nd character in the conf file, did you edit it manually? If so it's usually a curly quote that got in there by autocorrect.

  • hey a quick thanks first ill check it but i didnt get what do you mean edit it manually , is there some other way of editing it other then textedit

  • Nope checked it out the error my 1782nd character is coming in my wallet address and therefore it is not an escape character , i just change the mining pool to and it just gives the error

  • Sorry you didn't say what program you were using and I just assumed MacMiner! I tested xmr-stak-cpu with that pool and it didn't throw an error. Can you post the pool config here as is in your config.txt?

    THE MOMENT I changed pool address its gives
    JSON config parse error(offset 1749): Invalid value.

    i am using xmr stack on my hackintosh with 1080ti extreme

    it works fine with monero pool but as soon as i add pool address of xmr it gives error.Thanks for reply

  • i am using cmr stack amd for gpu. as i said it works fine on moneropool but gives error on nanopool setting i mentioned above

  • You have curly quotes around the pool. Copy paste standard quote marks from elsewhere in the config and be careful about autocorrect or edit in a code editor like Xcode rather than Textedit.

  • Pretty sure the curly quotes come standard or something. Just resolved my issue with the xmr cpu miner, which was the curly quotes even though I never touched them.

  • Is there any other config needed for xmr because just few minutes after my windows machine is reflected on nanopool but not mac one it is just showing new block found

  • @manshmedia said:
    yeah worked with xcode

    somehow textedit was adding something. NOw my problem is that with nanopool i am not seeing it on the interface of nanopool and i think it is taking double the time to submit result

  • What hash rate are you getting on the hackintosh and on the windows machine? I purposefully set the intensity very low by default to lower the risk to people's hardware. Edit the intensity here:

    { "index" : 0, "intensity" : 64, "worksize" : 8, "affine_to_cpu" : false },

    to a multiple of 8, so you could try 128, 256, 512, 1024 and see how it goes for you.

  • Device 0 work size 8 / 1024

    I think on minerpool it was fast , right here on nanopool my device does not show up as a miner , although i am getting results accepted message. I think on windows i am using tsv miner and its configured for nanopool and it shows up fine on nanopool monitor but this one just submits results , will keep it on for a whole night to see the difference
