[BUG] UnknownHostException when downloading Tesseract trained data using proxy #164

Closed eht16 closed 3 months ago

eht16 commented 3 months ago

Version

1.4.15.56

What platform are you using?

Android

OS Version

GrapheneOS Android 13

What happened?

When trying to download the trained data for Tesseract from within the app, an "UnknownHostException" is thrown.

This happens when a global proxy is set via "settings put global http_proxy proxy.example.com:8080"

The address in the error message is my configured proxy hostname.

@eht16 not sure what I can do about this. could this be an issue with your proxy being unable to contact github? I dont do anything special with http request so I guess they should work with proxy. can you access github using your global proxy from your browser?

edit: actually it is your proxy server the app can't connect to. thinking...

The proxy server can contact Github just fine, it works via browser and any other app and it can be resolved via DNS.

Argh, I denied the network permission when installing it.

After allowing the app network access, it works perfectly. Sorry for wasting your time :(.
