The logs are slightly different using [https://192.168.2.114](https://192.168.2.114):

I tried running the curl command on the server to check API access:

> curl -v -X POST [https://hosted.mender.io/api/management/v1/useradm/auth/login](https://hosted.mender.io/api/management/v1/useradm/auth/login)   
> -H ‘Content-Type: application/json’   
> -H ‘Accept: application/jwt’

and received the following:

> {“error”:“invalid or missing auth header”,“request\_id”:“ac8cd6d0-907a-4a73-a324-6522bdbe3c32”}

Should this have generated a JWT token? How can I get a valid JWT token?
