I am unable to use Jenkins to update test results due to an invalid credentials error. I have verified my username, password, and API keys are correct and I am still unable to login to Zepher.

Things I have done to resolve the issue

1. Regenerating my keys and using those as a way to resolve the issue and it still does not work.
2. Restarted Jenkins
3. Upgraded Jenkins
4. Upgraded the Zepher plugin
5. Downgraded the Zepher plugin
6. Downgraded Jenkins
7. Restarted the Jenkins Service
8. Restarted computer to run a clean version of Jenkins

Below is the following errors that occur after a test is run:
