btc-rpc-explorer + bitcoin-core + electrum-personal-server... explorer can't connect to electrum personal server (

I am running the above on a laptop PC under windows 10 - to have a local standalone bitcoin blockchain explorer.

They all seem to run fine in themselves.

But when the explorer (https://github.com/janoside/btc-rpc-explorer/) tries to connect to the electrum server (https://github.com/chris-belcher/electrum-personal-server) to pull in historic transactions on an address...

The log says btcexp:error Error 937gf47dsyde: Error: read ECONNRESET, json: {"errno":-4077,"code":"ECONNRESET","syscall":"read"}, userData: [object Object] (json: {"host":"127.0.0.1","port":50002,"protocol":"tcp"}) +10s btcexp:errorVerbose Stack: Error: read ECONNRESET

A local electrum wallet connects to the server fine - on the local address on that port.

It appears to be trying to connect to the right port etc... I don't know what to try next(!).
