Running GEX against a remote or configurable instance

[alexanderbez]

Is it possible to execute the gex binary that communicates with a Cosmos-SDK-based chain other than localhost or whatever is running locally? It would be nice to be able to run gex against either a remote node or a custom address/port.

I've tried that once and it did not work. Would like to find out why. Maybe it was due to some config or firewall.
An optional flag to input a remote node would be cool.

The port is configurable using for example gex -p 27657.
Which was mostly needed when running more instances on localhost.

But can it talk to a remote instance not on localhost?

no
