HTTPS POST requests not working in release build

[ioclaudio]

Hi,
In my case, the problem was on the server.
The full chain was needed.
This is the solution I’ve found:

Ionic-native/http/ngx v.s. @angular/common/http which should be used in an Ionic4 app?

Ok guys, I have solved. The problem was on the server. The server uses node.js, when I’ve replaced these credentials: cert: fs.readFileSync('./sslcert/chain.pem'), key: fs.readFileSync('./sslcert/privkey.pem') with these: cert: fs.readFileSync('./sslcert/fullchain.pem'), key: fs.readFileSync('./sslcert/privkey.pem') So the fullchain is required. Now httpClient seems to work both on Android and iOS. cld
