Proxy authentication error while setAccountInfo()

[Timm Suess]

I'm trying to connect from R to shinyapps.io behind a corporate firewall. I don't manage to authenticate my account via rsconnect::setAccountInfo.

Without setting any environment variables, I get a time-out:

> rsconnect::setAccountInfo(name='...', token='...', secret='...')

Error in function (type, msg, asError = TRUE)  :
  Failed to connect to api.shinyapps.io port 443: Timed out

After figuring out my proxy settings from the proxy configuration script, I have tried the following things:

• set RCurlOptions:
  

> options(RCurlOptions = list(proxy = "http://my.proxy:my.port")
> rsconnect::setAccountInfo(name='...', token='...', secret='...')

Error in function (type, msg, asError = TRUE)  : 

  Received HTTP code 407 from proxy after CONNECT

#same thing happens with the following settings:
> options(RCurlOptions = list(proxy = "userid:password@http://my.proxy:my.port")
> options(RCurlOptions = list(proxy = "DOMAIN\\userid:password@http://my.proxy:my.port")

• Added entries to the .Renviron file (including reboot of R after each ):

export all_proxy=DOMAIN\\userid:password@http://my.proxy:my.port
export https_proxy=DOMAIN\\userid:password@http://my.proxy:my.port

# in R console
> rsconnect::setAccountInfo(name='...', token='...', secret='...')

Error in function (type, msg, asError = TRUE)  : 

  Failed to connect to api.shinyapps.io port 443: Timed out

Timing stopped at: 0 0.08 42.59 

 

http_proxy=http://my.proxy:my.port/

http_proxy_user=user:passwd

https_proxy=https://my.proxy:my.port/

https_proxy_user=user:passwd


> rsconnect::setAccountInfo(name='...', token='...', secret='...')

Error in function (type, msg, asError = TRUE)  : 

  Received HTTP code 407 from proxy after CONNECT

• Used unsecured  connection method:

options(shinyapps.service_url = "http://api.shinyapps.io/v1")

> rsconnect::setAccountInfo(name='...', token='...', secret='...')

Error in function (type, msg, asError = TRUE)  : 

  Received HTTP code 407 from proxy after CONNECT

 Is there something I am missing?

Using internet2 (as suggested in ?rsconnect::rsConnectProxies) leads to another error:

> library(rsconnect)

> setInternet2(use = TRUE)

> options(rsconnect.http = "internal")

> rsconnect::setAccountInfo(name='...', token='...', secret='...')

Error in socketConnection(host = host, port = as.integer(port), open = "w+b",  : 

  cannot open the connection

In addition: Warning message:

In socketConnection(host = host, port = as.integer(port), open = "w+b",  :

  api.shinyapps.io:80 cannot be opened

Timm,

The 407 error implies the username or password is incorrect. It seems as though rsconnect package is talking to the proxy server, but the request is not being allowed through.

Problem solved - I used the following options combination, leaving out the domain information in the user name, which allowed me to tunnel through.

options(RCurlOptions = list(proxy = "PROXY:PORT", proxyuserpwd="USER:PWD", verbose = TRUE))
