I have the same issue (CMS Version 3.0.3 / IIS 10 / Windows Server 2019).  
I dont know if the issue is releated to [Someone can help to set up work with API (CMS version 3.0.0)?](https://community.xibo.org.uk/t/someone-can-help-to-set-up-work-with-api-cms-version-3-0-0/25364) or not.

Guys, i was finally able to obtain a access\_token!

What you have to do:

1. Open the path of your library. There should be a folder called “certs”
2. Inside this folder, create three new files:

- encryption.key
- private.key
- public.key

1. Go to [Online RSA Key Generator](https://travistidwell.com/jsencrypt/demo/) and generate a keypair. Copy the contents to the corresponding file (Private Key = private.key, Public Key = public.key)
2. Go to [Generate free random base64 string +\> GeneratePlus](https://generate.plus/en/base64) and generate a 32 bytes long base64-string. Copy your string to the file encryption.key.
3. DONE!

Create in Postman under “Headers” a new key:  
Key: **Authorization**  
Value: **Bearer**
