<![CDATA[agent tunnel not connecting]]>I have an agent tunnel on a remote site that, from what I can see in the agent log seems to be connecting. I see the node in the agent tunnel manager, but when i create and bind, it remains unbound and has a ? on the icon in infrastructure services. I do have other nodes from other sites that are working. I suspect this is related to something with the network the remote site has but I dont know what to request from them to allow through.
 I redacted some info with x's

SetupTunnel(<public ip here>): Agent certificate not provided

Can you check that agent certificate actually exist on machine with agent? What operating system agent is running on? What versions you are using?

Best regards,
