How to fix pandoc conversion failed with error 61

I recently updated R to 3.6.0 since then i can't knit any of my .RMD files without getting "Error: pandoc document conversion failed with error 61". I have searched and googled everything i can think of and can't find a solution. I also have no idea how i would get a recreatable file, but was hoping someone has seen this error or knows how to fix it?

Could not fetch http://?/UNC/ad/userfiles/***/R/R-3.6.0/library/rmarkdown/rmd/h/default.html
HttpExceptionRequest Request {

host                 = ""

port                 = 80

secure               = False

requestHeaders       = []

path                 = "/"

queryString          = "?/UNC/ad/userfiles/***/R/R-3.6.0/library/rmarkdown/rmd/h/default.html"
method               = "GET"

proxy                = Nothing

rawBody              = False

redirectCount        = 10

responseTimeout      = ResponseTimeoutDefault

requestVersion       = HTTP/1.1

}

(InvalidDestinationHost "")

Had the same problem and struggled for a while. I was behind a proxy (Windows 10) using Rstudio 1.3.1073 and R 4.0.3.

In my case additional "Invalid scheme" error revealed what was wrong. The automatic proxy setting did not have "http://" -part (scheme part) as needed by pandoc.

I added in .Renviron:

R_USER="C:\Users\myUserName\Documents"

http_proxy=http://my.proxy:8080

After restarting R, I was finally able to knit html-output with styled table (kable/kableExtra).

Apparently, one should not define a https_proxy.

This problem stems (at least in my case) from the fact that the used rmarkdown library is a network folder (in your case /UNC/ad/userfiles/***/R/R-3.6.0/library/rmarkdown/rmd/h/default.html). R cannot access this folder because rights are missing.

You have to change your default library to a place where you have full rights. For example "C:/Program Files/R/R-3.6.2/library".

In RStudio, click on Tools > Install Packages.. Under"Install to library" you can see the default option (in your case it should be/UNC/ad/userfiles/***/R/R-3.6.0/library/rmarkdown/rmd/h/default.html`). The second option here should be "C:/Program Files/R/R-3.6.2/library".

To change this order, i.e. to make the C:/Program Files/R/R-3.6.2/library (on Windows) or /Library/Frameworks/R.framework/Versions/3.6/Resouirces/library (on macOS) folder the default folder, you have to use the following code (execute the code in a new R file) :

bothPaths <- .libPaths()   # extract both paths
bothPaths <- c(bothPaths [2], bothPaths [1])  # change order
.libPaths(bothPaths )  # modify the order

After that, you might have to install the markdown package again. This time, it will be directly installed into the "C:/Program Files/R/R-3.6.2/library" folder.

Now, knitting should be working, because R will use the package straight from a folder where you have full rights.

I have a similar issue, since I upgraded de R 3.6 (using Ubuntu 18.04 64 bits, in case it matters)

Could not fetch
https://tiles.bcn.cat/tiles/XYZ/GuiaBCN/18/132633/97883.png

HttpExceptionRequest Request {   
host                 = "tiles.bcn.cat"   
port                 = 443   
secure               = True   
requestHeaders       = []   
path                 = "/tiles/XYZ/GuiaBCN/18/132633/97883.png"   
queryString          = ""  
method               = "GET"   
proxy                = Nothing  
rawBody              = False   
redirectCount        = 10  
responseTimeout      = ResponseTimeoutDefault
requestVersion       = HTTP/1.1 
}  
(InternalException (HandshakeFailed (Error_Protocol ("certificate has unknown CA",True,UnknownCa)))) Error: pandoc document conversion failed with error 61

As a result to hit knit on this document: https://gitlab.ajuntament.bcn/omd-gid/1905_pro_308_omd_curs_de_mapes_amb_r_modern_-_edicio_2020/blob/master/codi/09.mapes.Rmd#L1234

(anchor is to where that tile server is being called within the Rmd file)

Current pandoc (with R 3.6) is pandoc 1.19.2.4 Compiled with pandoc-types 1.17.0.5, texmath 0.9.4.4, skylighting 0.3.3.1 Which seems to be a bit old (Copyright (C) 2006-2016 John MacFarlane)

BTW, shall I open a new question on stack overflow, or maybe it's ok to place it here since it's somewheat related to yours, and we have both potentially related items aggregated together?
