Error message: HTTP 406 Not Acceptable

This error will show if the client sent a hypertext transfer protocol (HTTP) header, which the server cannot accept. The expected header can be found in the official TAXII 2.0 specification. This might happen if the client is not correctly configured to use TAXII 2.0 as its protocol, and instead uses TAXII 1.x or TAXII 2.1.

Make sure that you specify that the server is TAXII 2.0.
If this does not solve the problem, contact our Customer Support team with this information:
- The name of the client
- The version of the client
- All logs that you can export
- A timestamp of when the error occurred
Note: This information will be extremely valuable for further debugging.
