Ionic v4 and ngx-socket.io

Hello, I have a problem that I can not solve. My v4 ionic application works great with ngx.socket.io locally and on my device.
Nevertheless, after having built --prod - on the connection is blocked, I can not even debug and know why I’m here all there is to do … How to do?

I connect to an external node.js server to my application, I do not see why I connect to an external node.js server to my application, I do not see why with “run android” it works and after the build everything is blocked

thank you for your help
(sorry for my english i’m french =))

I just tested and it works with the app-debug.apk … I’m lost! I’m sure it’s a licensing concern with config or manifest

getting the same issue

I dropped the sockets, so I found another system with the observables

I made progress with it and it has to do with in the config.xml you need to git it <allow-navigation href="*"> to allow access everywhere. I solved it, then saved and reversed the solution so now I am backtracking hahah

it is not woking >> vv
