"Unknown Error" when logging in to Docker Hub

I’m trying to login to Docker Hub via Docker Desktop for Windows but when I use my login I get an “Unknown Error” message.

I’m running Windows 10 Enterprise for the OS.

I’m a contractor and set up my ID using my company’s email, not who I’m contracting with. Could this give an error when trying to access the repo for the company I’m contracted with?

Any other suggestions as to what is happening are welcome. The error message is very vague.

I’m not sure what the commenter Paulo means by: " Just make sure your password contains special characters like http://USER:MyAwesome@Password@proxy.org:PORT must be http://USER:MyAwesome%40Password@proxy.org:PORT"
