When this issue came up previously we had some back and forth internally about how to handle it but it was never fully resolved. I originally had implemented a draft of an IgnoreSslError flag similar to what the WebViewer provides, but the only reason we did that for WebViewer was due to the fact that it wasn't possible to specify alternative root certificates. With the Web component, we do have the option of providing our own validation so the alternative proposed approach was to allow people to specify a custom root certificate to handle situations where servers were providing self signed certificates.
If your server is on the public internet and has a domain name, your best option would be to use LetsEncrypt to get a valid certificate and therefore is the lowest effort solution.
