When I try to connect I get "Please check your wallet and daemon log for errors. You can also try to start monerod manually."

From bitmonero log... (below)

*:WARNING,net:FATAL,net.p2p:FATAL,net.cn:FATAL,global:INFO,verify:FATAL,stacktrace:INFO,logging:INFO,msgwriter:INFO 2018-05-07 21:36:09.033 0x7fffc70cd3c0 ERROR msgwriter src/common/scoped_message_writer.h:102 Error: Couldn't connect to daemon: 127.0.0.1:18081

Suggestions very gratefully received! Many thanks

  • Which operating system are you using? Also, have you looked at that ^ guide already? – dEBRUYNE May 08 '18 at 12:50
  • Thanks for getting back to me... macOS sierra 10.12.6

    Yes I have been trying to follow your guides rather than ask repeat questions! I am thinking at this stage that it might be best to resync and start afresh. Another additional issue was that I was waiting for a transaction from binance that never came through to the wallet. I was trying to fix that problem when it crashed and I now have the daemon issue too.

  • I checked https://xmr.llcoins.net and got the msg “Your private key is invalid. Please check it and try again.” To my relief this website - https://xmrchain.net - does confirm my transaction, why the difference?? – beta beta May 08 '18 at 18:16
  • A few questions first. 1. Did you upgrade to GUI v0.12 before or after April 6? 2. What exactly crashed? Did your PC crash whilst the GUI was syncing? 3. Did you send funds to your "main" address (the one starting with a 4) or to one of your subaddresses (the ones starting with an 8)? – dEBRUYNE May 08 '18 at 18:39
  • I was sure I had downloaded GUI after April 6, however looking in my download folder it says the app was created/modified 3 April 2018 at 12:45, could I have downloaded an older version after April 6?
  • The macbook crashed, freezing for an extended period and with force quit not an option I held down the power button and reloaded. The GUI may well have been syncing at the time, it had connected and daemon synced, but frequently needed to re-sync and re-connect whenever I had GUI open

  • If your Macbook crashed whilst the GUI your blockchain is, most likely, corrupt. Try these steps: 1. Go to the Settings page of the GUI. | 2. Enter node.moneroworld.com in box 7 (see -> https://github.com/monero-ecosystem/monero-GUI-guide/blob/master/media/black_settings.png). | 3. Enter 18089 in box 8 (see -> https://github.com/monero-ecosystem/monero-GUI-guide/blob/master/media/black_settings.png). | 4. Click in another (empty) box (on the Settings page) to ensure your settings are properly saved.| 5. Exit the GUI and make sure to stop the daemon as well. [1/2] – dEBRUYNE May 08 '18 at 20:22
  • Delete data.mdb from C:\ProgramData\bitmonero or ~/.bitmonero (Linux and Mac OS X) | 7. Restart the GUI (+ daemon). | 8. If the GUI feels laggy / buggy for you, apply this guide -> https://monero.stackexchange.com/questions/6651/my-gui-feels-buggy-freezes-all-the-time | If you need any further assistance or incur any issues, please let me know.

  • Thanks for your help and patience, I followed your steps and wallet and daemon both now synced, but still no balance or history of any transactions... As I mentioned, I checked xmr.llcoins.net and got the msg “Your private key is invalid. Please check it and try again.” xmrchain.net however, does confirm my transaction, which is confusing me – beta beta May 08 '18 at 22:00
  • What's the Wallet creation height (on the Settings page of the GUI under Debug info)? – dEBRUYNE May 09 '18 at 08:55
  • Can you change that to 1350000 and let the wallet refresh? – dEBRUYNE May 10 '18 at 09:39
  • Just to check before I do that I got the following message...

    "Are you sure you want to rebuild the wallet cache? The following information will be deleted

    • Recipient addresses
    • Tx keys
    • Tx descriptions

    The old wallet cache file will be renamed and can be restored later.

  • i.e. should I refresh the wallet and, worst case scenario, the funds don't appear, would I still be able to prove the transactions had occurred from my seed alone? – beta beta May 10 '18 at 18:21
  • "The old wallet cache file will be renamed and can be restored later" - your old private tx keys (to prove you sent funds) will be in that file. Note that you cannot retrieve the private tx keys by restoring from the 25 word mnemonic seed. – dEBRUYNE May 10 '18 at 19:52
  • OK thanks I have now changed the wallet creation height to 1350000, and reloaded, sadly the balance is still 0, with no history of any transactions. – beta beta May 10 '18 at 20:03
  • Are you sure you have the right wallet open? You can check the wallet name on the Settings page of the GUI under Debug info. – dEBRUYNE May 10 '18 at 20:13
  • Sorted! I had opened a second wallet, and your recent changes applied to that have worked...Big relief and thanks again for all your help – beta beta May 10 '18 at 20:52
