Invalid credentials assistance

When I run
source scripts/start_lab.sh, it returns
"An error occurred (InvalidClientTokenId) when calling the DescribeDBInstances operation: The security token included in the request is invalid.

An error occurred (AuthFailure) when calling the DescribeSubnets operation: Authorization header or parameters are not formatted correctly."

I guessed it was incorrect credentials and checked for them- I found

I am confused why this happened- did I consume all the resources and they were eventually deactivated?

Hello @Dan_m
Please, reboot the lab’s server and try again in a fresh lab session. If the issue persists, please fill out this lab refresh form.
