How to troubleshoot "connection timeout" when a db connexion is started

[DanielCastronovo]

Hello, how to troubleshoot this kind of error ?
I've setup teleport & teleport-agent with Helm chart on AWS.
I tried to connect to an instance of type db, but when i send a command, i've an error.

tsh db connect --db-user=test elasticache
localhost:35871> stats$
(error) ERR Teleport: connection timeout
(22.93s)

No errors on teleport & teleport-agent pods.

I would start looking at the Teleport agent logs.

This looks like it doesn't have AWS credentials.
