After launching Explorer, I can see the database getting updates (block_tx 180 184 commit e.g.), but also the above message appears and when checking in a browser, the status of the blockchain shows "no connection", even though the number of blocks is correct and keeps updating, so Blocks***.dat file gets red.
It sounds like RPC is not accepting connection from Mce? How can I get Mce to connect?
Just found out... By adding rpc port in multichain.conf. Sorry for trouble.
