I could not say 100% what is the problem, but one thing I can see is that the console doesn't say anything about the tcp server on port 50001 being started.
So it's not matching with what I've written back then:
After starting Fulcrum (start.bat) it might take an awful lot of time until everything is sync-ed. You may want to look for lines like:
[2023-02-27 21:42:48.964] Starting listener service for TcpSrv 127.0.0.1:50001 ...
[2023-02-27 21:42:48.965] Service started, listening for connections on 127.0.0.1:50001
or
[2023-02-27 22:03:32.758] <Controller> Block height 778553, up-to-date
Yeah I can confirm that it only tells me about listening for the HTTP thing, and not opening 50001. I think because Fulcrum still thinks there's more blocks that should be there. I've added
maxblockheight=606010 to Fulcrum confguration file, and deleted Fulcrum data directory, I am syncing Fulcrum from scratch again and will see how this goes.
