the system tries again using UDP. The request might
fail, for example, if the receiving endpoint only accepts
incoming connections over UDP.

request fails, the system tries again using TCP. The
request might fail, for example, if the receiving
endpoint only accepts incoming connections over
TCP.
• TCP Only: Select to only use TCP.
• UDP Only: Select to only use UDP.
Select Yes or No to enable or disable secure
