AWS - RDS console issue

I am having issues with the RDS console. Unable to create DB
instances. Please find the screenshot below. Please help me to fix
this ASAP.

Has the playground expired? It only lasts 3 hours.

Hi @al1 , No I just launch the aws playground and logged in with creds and trying to create rds. It is showing error as signature expired

Are you following the guidance under the RDS heading on this page:
