1. The problem I’m having:
When making requests using my Flutter app I often get TLS errors. The issues show up in mobile app and Linux app but not in the web browser app.
The weird part is that it does not always have issues. If I constantly spam the curl command or reopen the apps sometimes the contents shows up there and it has no TLS issues.
Another strange thing. If I build release APK and install it on the phone and it doesnt work. If I launch it using debug tools everything works smoothly.
What I’ve tried so far:
- Changing the max TLS protocol to 1.2 which seemed to improve things a bit but still not perfect.
- Using native HTTP clients in the implementations. Not much improvement.
Another thing I discovered. If I do curl localhost:2019/config/, sometimes its responding with configuration for one subdomain and sometimes its responding with the config of the other.
