proxy/connection problem with tidyRSS (http vs https)

Hello,

I am experiencing problems with my proxy/internet connection with the tidyRSS package. I am trying to run the following example in the tidyRSS vignette:

library(tidyRSS)

rss <- tidyfeed("http://andrewgelman.com/feed/") 

But I get the following error message:

Error: $ operator is invalid for atomic vectors

To get more information, I tried:

httr::GET("http://andrewgelman.com/feed7")

Error in curl::curl_fetch_memory(url, handle = handle) :

Timeout was reached: Recv failure: Connection was reset

It seems that if the url I am trying to access is http then it works, for instance:

rss<-tidyfeed("http://bactra.org//weblog/index.rss")

But if the url is https instead of http (it seems that the http redirects to https) then it does not work.

I am using a proxy conection at the office, and I have tried to modify several configuration options in RStudio but I still have isuues with this.
In Tools - Global Options - Packages, I have unchecked the option "Use Internet Explorer library / proxy for HTTP".
If I type Sys.getenv("http_proxy"), it gives me the correct proxy.
Do you have any suggestions?
Could you please help me to solve this problem?
Let me know if you need more information.

Thank you in advance.

It sounds like this happens when the port you're trying to use is blocked by a firewall:

If you can eliminate that possibility, and still are running into this problem, you might consider filing an issue in the GitHub repo for tidyRSS:
