Wallet do not synchronizing because he couldn't connect to daemon. Win 10. Restore height is 2150000.

I tried:

  • Reinstall GUI (I had used latest version (17.4) before, but anyway)
  • Start monerod
  • Resync whole blockchain (I nearly download it, but it stopped at 7k blocks before syncing and don't want to sync again).
  • Start monerod x2 (it automatically closes after "initizatiling core" after 1 second)

Bitmonero says:

    This exact what I get too. The problem is, do not start the monerod before starting the GUI. The GUI starts the daemon a second time, if it already runs or not. The first instance blocks the ports for the second. That's a flaw in the GUI. A logical error within the GUI from my point of view.

It could be two things.

  1. Your firewall is blocking the daemon from working. Try allowing a new firewall for monerod.exe

  2. There is something that is using port 18080. If you know what program uses this port, close it before starting monerod.exe
