[Blink] SSL certificate verification error when dialing out

[Jeff Pyle]

Lars,

The root cause of your problem here is the same as the problem you
described in the thread "[Blink] Expired certificate for Ubuntu Focal
Repository?"  The proxy servicing sip2sip.info is using the same style of
Let's Encrypt certificates.  The solution should be the same, too.


Regards,
Jeff
