If TLS encryption is required, select a valid certificate here.
To use the secured TLS or MTLS network protocols, you will need a server certificate. This certificate must have been signed by a certification authority. Click on the "Certificate..." button to open a window for selecting a certificate. Then, select the appropriate certificate and confirm it by clicking the OK button. Information about the selected server certificate will then be displayed.
The configured certificate is also used for the encryption of the connection from the TLS UCServer to XMPP Proxy. If no certificate is selected, between UCServer and XMPP Proxy only an unencrypted connection can be established.
