HTTP error messages: "Server never wrote a response" #2734
Description
When starting Pluto today, I encountered some errors. Pluto starts nonetheless and works just fine, but this happened every time I started Pluto again.
Here are the error messages:

└ @ HTTP.Servers ~/.julia/packages/HTTP/SN7VW/src/Servers.jl:483Then some Gtk warnings, and finally the server starts just fine. I can run notebooks normally, so I am not sure if this is important or not, but thought I would signal it anyway.
I am using Pluto v0.19.32 on:
