When trying to access the Qlik Sense Management Console (QMC) or Hub, the message HTTP error 431 returns the status code:

Request header fields too large

Environment

The HTTP 431 Request Header Fields Too Large response status code indicates that the server refuses to process the request because the request’s HTTP headers are too long.
There is a limitation on HTTP Header size in Windows and Qlik Sense follows it.
The maximum header length is 16 KB.

Follow the instruction from that article - Qlik Sense HTTP Header size restriction
For the microservices please change the header size in services.conf.
