Error validating provider credentials: error calling sts:GetCallerIdentity: RequestError: send request failed

I changed by windows password. After that I started getting below error when I login to AWs via gitBash. Not able to run any Terraform commands. I am doing proxy_on with new passowrd. Also, tried with old password. How can I fix this?

" error validating provider credentials: error calling sts:GetCallerIdentity: RequestError: send request failed

caused by: Post https://sts.amazonaws.com/: Forbidden "

I’m also seeing this on a fresh install,
MacOS Catalina 10.15.3
Terraform: v0.12.20
aws plugin v2.56.0_x4

I have to set to debug as it fails around 12 times with the message Send Request sts/GetCallerIdentity failed, caused by: Post https://sts.amazonaws.com/: net/http: TLS handshake timeout after around 12 tries it finally succeeds but during that time any requests made from my machine fail if they require a dns lookup.

Using 1.1.1.1 as my only resolver while testing this

Tried using 8.8.8.8 as well same situation

Any updated on this??
