Hello, I am currently encountering an error when trying to use the keggList function from KEGGREST in Windows. I am trying to retrieve pathways from the arabidopsis database but am encountering the following error (see code). I have re-installed KEGGREST and this function still isn't working. Googling the issue suggested that the error could be due to the KEGG API moving from http to https. If so I do not know how to change the getUrl function to reflect this. Any help would be greatly appreciated.

keggList("pathway","ath")
Error in curl::curl_fetch_memory(url, handle = handle): Failure when receiving data from the peer
Traceback:

1. keggList("pathway", "ath")
2. .getUrl(url, .listParser, nameColumn = 1, valueColumn = 2)
3. GET(url)
4. request_perform(req, hu$handle$handle)
5. request_fetch(req$output, req$url, handle)
6. request_fetch.write_memory(req$output, req$url, handle)
7. curl::curl_fetch_memory(url, handle = handle)

What version of Bioconductor are you using? Is it possible to update your version of R and therefore Bioconductor? I see you are using R 4.1 which means 3.13 or 3.14 -- I currently cannot reproduce this using Bioconductor 3.16/3.17 but can using 3.14 so it seems like it was corrected in a more recent version of the package.
