Failed to download extension

[rafapereirabr]

I'm having a small issue when trying to install {duckdb} extensions on my Windows machine. I suspect this is because duckdb is pointing to a http url, instead of a https url. See reprex and R session below.

ps. I had no problem running this code on my personal computer (Windows), but this has been a persistent problem in my computer at the office (also Windows).

reprex

library(DBI)
library(duckdb)
library(tidyverse)

con <- dbConnect(duckdb::duckdb(config=list('allow_unsigned_extensions'='true')))

dbExecute(con,"install httpfs;")
dbExecute(con,"load httpfs;")

Erro: rapi_execute: Failed to run query

I have a similiar issue. specifically in a webassemly environment. Please let me know if this should be a separate issue.

I think that is duplicate of #66

but this has been a persistent problem in my computer at the office (also Windows).

Could it be a proxy issue?
You should check duckdb/duckdb#13368
In general, it is a good practice to check if it is an R-specific problem or if the same problem occurs with other clients.
I recommend to check if the same error occurs in the CLI.
