Pluto Remotely, using Flux causes "Distributed.ProcessExitedException(3)"

[RohanRajagopal]

I am using Pluto notebooks remotely on a Windows Machine.

However, using the following command causes an error

using Flux

The following is the complete error message

This is a problem even if I use the same command in the remote server directly. All the scientific computing packages that I have used in the Pluto notebooks have been working without any problem. It is just the Flux packages while using in Pluto notebooks that causes an error.

Additionally, to clarify, Flux works on the REPL.

Deeply appreciate any help, thanks very much.

Thanks for the report @RohanRajagopal ! Could you say a bit more about 1) your remote setup, and 2) about this observation:

This is a problem even if I use the same command in the remote server directly.

Could you give a short description of this that we can reproduce?
