When I try to connect to my instance from Studio, everything seems fine until authentication on "SYSTEM", "manager" login, then I get an error "The system is not reachable, the login data could not be considered." Has anyone faced this situation or found a solution?
According to Juergen's blog, this can sometimes be solved by accessing via PuTTY using the IP. After creating a public ppk key from the pem key and exposing it in pageant, I try to access the Elastic IP to try to re-start the DB, but PuTTy simply hangs. PuTTy works fine with other IP addresses.
Something seems wrong with the Elastic IP address, or perhaps I'm doing something basic wrong. Does anyone have suggestions on this? Is there a forum where we can communicate with Juergen, since he closed his blog comments?
