Test connection failed HTTP return status code was 400

Is there any reason why an unused connection would give this error when trying to use it out of the blue. The last time it was used it was successful, about 2 to 3 weeks ago. I am using SGC for Microsoft Intune. I have disabled all scheduled configurations because I do not want to inadvertently pull back all CIs from Intune while modifying workflow configs. 

Alert level: Critical.

Test connection failed.

Reason: Unable to make a connection to Intune API call. Please check your credential configuration. Check system log for more details. HTTP return status code was 400

Suggested solution: Indicates an error has occured. Further debugging is required.
