Async test failing locally with connection refused

[adigitoleo]

For me (Arch Linux, julia 1.6.1) the async test is failing with LoadError: IOError: connect: connection refused (ECONNREFUSED). I think this stackoverflow answer might be relevant, but I'm not very experienced with async stuff.

Just tested on Win10 and got the same error.

My julia version (Arch Linux):

Whoops, looks like this has been fixed in 1220949

[adigitoleo]

Tests are passing using latest master. I'll close this. Maybe you can tag a new release soon?
