I am not sure how to fix or configure my computer to overcome this error and it is preventing me from performing several tasks including uploading to my shinyapps.io cloud server.
> devtools::install_github('rstudio/shinyapps')
Error in curl::curl_fetch_memory(url, handle = h) :
Unsupported proxy 'https://localhost:1410/', libcurl is built without the HTTPS-proxy support.
I have the issue with the rsconnect as well which prompted me to try the different approach, do you have a good link, or any guidance on how to overcome the http proxy issue?
You have a local proxy running. I have no idea what software that is, so I cannot direct you.
If you cannot disable the proxy, and it is there because of your IT department, I would suggest reaching out to them for help.
