Sign in failed (application)

Hi, I am using KNIME at my workplace, which was all approved.

The first few days was completely fine as I was able to sign in via the application. If I clicked ‘sign in’ it would just load up the web, automatically sign in and close the web.

However, after those few days I have been unable to log in and I am unsure as to why. It keeps giving me this error, any thoughts?
