Replicating a ping request from curl cmmand using the httr package

I have some trouble replicating some curl command in the r package httr:

Unfortunately I cannot provide reproducible example as it is within a secured network. But I hope the comparison of the curl request and httr request allows for some analysis.

This is the curl command, working fine:

curl --location --request GET 'https://test.com:443/a/b/ping' --header 'system-auth: __token1__' --header 'Authorization: __token2__'

I try to replicate this behavior using the httr package:

endpoint = "/a/b/ping"
proxy <- "https://test.com:443"
token1 <- "__token1__"
token2 <- "__token2__"

header <- httr::add_headers(.headers = c("system-auth" = token1, "Authorization" = token2))
result <- httr::GET(paste0(proxy, endpoint), header = header)

With the httr request I receive the following error:

* OpenSSL SSL_read: SSL_ERROR_SYSCALL, errno 104
* stopped the pause stream!
* Closing connection 0
Error in curl::curl_fetch_memory(url, handle = handle) : 
  OpenSSL SSL_read: SSL_ERROR_SYSCALL, errno 104

So I am looking for ideas how to change the httr request to make it work or an explanation why the result of the curl command and the request via httr differ.
