On the libcurl discussion thread, I am referred to this issue: 
https://github.com/curl/curl/issues/5356

On FreeBSD 12.2-RELEASE, the version of OpenSSL is 1.1.1k and curl is 
7.73.0
If I'm not mistaken, then the problem seems to come from the firmware of 
the device.
I think I can fix it by testing the https connection and if it fails 
switch to http connection.
