Secure connection to Server instructions (https)

Within the Training environment

If you want to connect to the virtual training machine using the secure (https) connection:

  • Launch your web browser (or in your R script)

Note: You will get a warning when connecting to 8443 because the SSL certificate is self-signed.

  • On the warning screen, click “advanced”

  • Then click “accept risk and continue”

  • This is secure because you are connecting over a local network, so there is no danger of external threats connecting to you.

On Windows


If you are having problems connecting to an Opal Server over https, and are getting an error message like:
Error in curl::curl_fetch_memory(url, handle = handle) :
schannel: next InitializeSecurityContext failed: SEC_E_UNTRUSTED_ROOT (0x80090325) - The certificate chain was issued by an authority that is not trusted.

this can be resolved by changing the curl backend to openssl. This can be done by calling the R functionSys.setenv(CURL_SSL_BACKEND = "openssl") or by adding the line CURL_SSL_BACKEND=openssl to the “.Renviron” file in your R project.
