REST API Request Limit - Error 'Bad Message 431 reason: Request Header Fields Too Large'

cm00001 over 5 years ago

Hello,

Today when trying to turn off a rule inside a Web Policy using a REST API call, I got a server from the error:

Bad Message 431 reason: Request Header Fields Too Large

This happened after I added another rule to the policy. In other words, the request I submitted to update the policy, was over the allowed limit allowed by the web server to process.

https://docs.sophos.com/nsg/sophos-firewall/18.0/API/PROTECT/Web/WebFilterPolicy/operations/AddPolicy&UpdatePolicy&UpdatePolicyfromAPI.html

This being said, does anyone know how to configure this parameter (either through the web interface or CLI) to allow for larger REST API requests?

Thank you!
