From the docs:
PreferServerCipherSuites is a legacy field and has no effect.
It used to control whether the server would follow the client's or the
server's preference. Servers now select the best mutually supported
cipher suite based on logic that takes into account inferred client
hardware, server hardware, and security.
As of Go 1.16, functionality provided in io/ioutil has been depreciated
in favour of the io or os packages. Now that Go has been
upgraded in go.mod, the linter will not pass without these changes.
The last bugfix added some explicit header fields in an attempt of
fixing an issue with error responses. Unfortunately they weren't
strictly needed for the fix but ended up causing issues in a non-error
case.
This commit removes those header fields again and makes sure the "auth
header not found in response" header doesn't occur anymore.
