If TLS negotiation fails during a certificate exchange, try the following actions to resolve the issue:
Install/re-install the root and all intermediate certificates provided by your CA on the SBC.
Ensure that SBC's FQDN configured on the Teams side is identical to the one on SBC's certificate.
Wildcard certificate exchange – Ensure the correct number of spaces exist before the domain name. For example, a wild card certificate generated for "
*.example.com" is not valid for "
*.customers.example.com". Refer to article Configure SBC for TLS for a details on SBC-supported certificate format.
