Extension - Intermittently taking 5 seconds to get first router channel open during local testing

[huntharo]

Motivations

• Possible issue with the http2 socket open taking too long
• The 5 second duration feels like a DNS drop, which is odd considering this is local
• Might need a timeout on waiting for the response from the router and canceling the invoke if no response in time
