This error seems to present due to multiple logged in sessions to Connect/Cloud/Command Center overtime. Microsoft shared this as a more detailed explanation:

The error message you are encountering indicates that the request header section exceeds the maximum allowed size, which is set to 8192 bytes. This issue can occur when the HTTP request being sent to the server contains headers that are too large, often due to excessive cookies or other header information.
