Technical Tip: Windows Agent or OWA agent producting 405 errors in logging

This article discusses about 405 errors in Windows Agent or OWA Agent logs. 

This is usually due to an incorrect API key (link to KB to create a new key will be below) or the interface of the FortiAuthenticator is not setup to receive REST API calls.

- Log into the FortiAuthenticator and go to System -> Network -> Interfaces.

- Check the box with the network facing interface(s) that will be receiving REST API calls then select 'Edit'.

- Ensure 'REST API (/api/)' is enabled under: Admin Access -> HTTPS (TCP/443).
