TLS errors using Chilkat library to access Microsoft Graph APIs

I've been trying to use Chilkat library to play around and learn about using Microsoft Graph APIs but it seems I keeps getting TLS errors (connectFailReason 109) with even the simplest GETs and POSTs. This is what a typical log looks like:

The library is not the very latest version but it isn't TOO old (about a year and a half - version 9.5.0.86). I didn't want to upgrade just yet because I have some "live" projects using this dev box (and this is just a "learning journey") so I was wondering if anyone can tell me whether the library version is the most likely issue or whether, perhaps, I'm missing some simple settings in the CkHttp object - the only thing I really do with it is set the auth token (which seems to have been retrieved correctly judging from the logs I output.

The actual API calls are pretty straightforward - mostly simple (slightly modified) examples from Chilkat website. But even the simplest http.quickGetStr("https://graph.microsoft.com/v1.0/me"); fails with a log similar to the above.

So, if anyone can suggest any properties to set to ckHttp to solve this issue (or confirm that library needs to be upgraded to access graph.microsoft.com - if, indeed, that is the case) - I would greatly appreaciate it.
