Using TCP load balancer for several years, while the connection started timed out recently, the successful late is 10-40%, checked by either curl or nc like:
curl https://<our-domain.com>/our/app
curl: (28) Failed to connect to <our-domain.com> port 443 after 16239 ms: Couldn't connect to server
nc -z our-domain.com 443; echo $?
1
Is there any way to add more resources to reduce the timeout, or at least see the log of what is happening on the TCP load balancer?
