Hi, I’m trying to configure a certificate to MS Teams SBC.
In Teams I have 2 domains prueba.es ans centralita.prueba.es.
At now, I’d created a cert for centraliota.prueba.es and for user firstname.lastname@example.org works, but for user email@example.com I cannot received calls with SBC.
Microsoft told me that the problem is that in the cert I have to add both domains, prueba.es and centralita.prueba.es.
So, I’d tried to add both domains with:
./letsencrypt-auto certonly --standalone -d centralita.prueba.es -d prueba.es
But I get a error with prueba.es:
Detail: Invalid response from
[ip address]: “\n\n404 Not
To fix these errors, please make sure that your domain name was
entered correctly and the DNS A/AAAA record(s) for that domain
contain(s) the right IP address.
prueba.es is a domain of my company and use port 80.
Can I only add second domain in cert? Anyone has this problem with MS Teams?
