Apparently BCHCTL can quit working permanently:
":~$ bchctl getinfo
Post "https://localhost:8334": dial tcp [::1]:8334: connect: connection refused"
even if rpcuser/pass matches both .conf files
SOLVED !
DELETE /HOME/USER/.BCHD/DATA/MAINNET/BLOCKS_FFLDB/METADATA
and download the entire blockchain again,
even though you already have the whole dataset on disk.
no firewall
":~$ ss -tuan"
reports 8334 is not being listened to by anything,
suggesting BCHD has simply abandoned the external control path
delete both .conf does not fix.
