I've been trying to upgrade my DDNS from HTTP to use HTTPS connection but so far I've been unsuccessful.
I've got myself a certificate to use:
By using the DNS challenge:
and then tried to export the certificate to my pc and uploaded it to router's etc/ssl/certs location like "/etc/ssl/certs/mycert.cer":
but whatever I do, I never seem to get the system to use it instead of the OpenWRT certificate:
I have libopenssl3, wget-ssl, ca-certificates and ca-bundle packages installed on system.
