API call threw SSLException whenever I try to authenticat from dhis capture mobile app after setting up https

After setting up ssl certificate and making my connection to dhis htttps, I become unable to connect and authenticate from Dhis2 capture mobile ap, it just say API call threw SSLException, does this has something to do with the nginx server settings, any help would be appreciated.

Never mind, It was nginx server issue and I fixed it, thanks
