| Source | Live Communications Server |
| Description | A configured transport has failed to start. Transport TLS has failed to start on local IP address 0.0.0.0 at port 5061. |
| Event Information | According to Microsoft: Cause 1: This can occur due to a configuration error, low system resources or because another program is using the specified port. It can also happen if the IP address specified has become invalid. Resolution: Ensure that the IP address specified is valid and that no other program is listening on the specified port. CAUSE 2: This issue occurs if the certificate that the TLS listening port is configured to use is renewed while Live Communications Server is running. When the certificate is renewed, the access control list (ACL) entries are lost. These entries were configured on the certificate when you configured the TLS listening port. Without the ACL entries, Live Communications Service cannot access the certificate. This issue may occur if your domain has a Group Policy object that is configured to automatically renew certificates. RESOLUTION: To resolve this issue, reconfigure the TLS transport to use the new certificate. Additionally, verify other connections that are configured to use the same certificate. Note:These other connections may include Mutual TLS connections and routing connections, To reconfigure the TLS transport to use the new certificate, follow these steps: 1. Start Live Communications Server. 2. Expand Servers, right-click the server where you want to reconfigure the TLS transport for the new certificate, and then click Properties. 3. Click the Connections tab, click the connection that uses TLS or the connection that uses TLS Mutual transport, and then click Edit. 4. Click Change Certificate, click the new certificate in the Select the certificate you want to use list, and then click OK. 5. Click OK, and then click OK again. 6. Stop and then restart Live Communications Server. |
