This type of error can be related to certificates. Are you using a CA-signed certificate on your Expressway E?</li></ol>

<span style="font-size:12.0pt; color:black">I've racked my brain on this. I cannot get a call from the cloud to the on prem CUCM to work. On-prem to cloud works fine so I know Expressway to cloud TLS is working etc. I've attached a screen shot of the call leg
from expressway -E where the call gets rejected with 404 not found. I can ping and resolve cluster1.domain.com (which is the pub).</span></p>
