After upgrading 9.x to 10.x the /api throws "404 - not found"
If after upgrading your self-hosted helpdesk from "9.x" to "10.x" all API calls start returning "404 - File or Directory not found" try this:
Open the file "
Open the file "
C:\Windows\System32\inetsrv\Config\applicationHost.config
" and check if there's a section that configures access to "/api" location. Something like: <location path="Default Web Site/helpdesk/api"> <system.webServer> <security> <authentication> <anonymousAuthentication enabled="true" /> </authentication> </security> </system.webServer> </location>
Simply remove that section and it should work. It was required for older versions, but not the one based on ".NET Core" (aka NET 5 and later)
