Won't connect to electrum-personal-server-windows-release-v0.2.4

[pperrin]

I have the latest bitcoin-core and electrum personal server - (a local electrum wallet seems to connect fine) but starting explorer gives me this...

npm WARN config global `--global`, `--local` are deprecated. Use `--location=global` instead.

The connection to the server at 127.0.0.1:50002 fails - but it works fine for a local electrum wallet...

What am I doing wrong? Or what can I do to find out more about what is going wrong?
