Hello Amin
I have been trying to setup a TLS extensions using my FreePBX 13.0.194 with Yealink phones.
I am having my FreePBS behind my Firewall. All the ports 5061 (TLS), 11000 - 11200 (RTP) are forwarded to my FreePBX internal IP.
I am using dyndns.org for my domain name. The below error comes when trying to generate a Let’s Encrypt certificate.
There was an error updating the certificate: HTTP Challenge for fasil.dyndns.org is not available. Whole response: {“type”:“urn:acme:error:unauthorized”,“detail”:“No registration exists matching provided key”,“status”:403}
I have tried to setup the TLS extension with self signed certificate in the local LAN. Could you please help me out here ???
Thanks.
