Unable to connect to RDS after new OS update maintenance

0

Hello I can no longer able to connect to our PostgreSQL after a system-update (new OS maintenance). I checked

  • security group
  • Logs (database is up and running according to log)
  • End point (still the same)
  • I tested the connection with nmap and telnet to check port 5432 but not getting response.

Can anyone give me an advice?

Hello, The best practice here would be to open up a support case so that the team can check the RDS instance and parameters. If the SG, NACL groups etc are not the issue. The host could be having issues. Did you try logging into the host machine ? What is the state it is in ?

  • required – The maintenance action will be applied to the resource and can't be deferred indefinitely.

  • available – The maintenance action is available, but it will not be applied to the resource automatically. You can apply it manually.

-next window – The maintenance action will be applied to the resource during the next maintenance window.

  • In progress – The maintenance action is in the process of being applied to the resource.
