We are receiving the following errorr when doing an npm install

npm ERR! Error while executing:<br>npm ERR! C:\Program Files\Git\cmd\git.EXE ls-remote -h -t https://oauth2:{xxxxxx}@git.mdbootstrap.com/mdb/angular/ng-uikit-pro-standard.git<br>npm ERR!<br>npm ERR! remote: HTTP Basic: Access denied<br>npm ERR! fatal: Authentication failed for 'https://oauth2:{xxxxxx}@git.mdbootstrap.com/mdb/angular/ng-uikit-pro-standard.git/'<br>npm ERR!<br>npm ERR! exited with error code: 128

Where xxxxxx is our token.

I have tried deleting node_modules and doing another npm install but I am always presented with the same error

Please advise on how to correct this.
