Flask does not work in termux without Internet

I have python flask server and run it in Termux. Then I have access to this server with address
It works on some Android phones. But there are some models don’t work with this application without connection to the Internet. It seems strange.
Is there a way to allow this app to work without Internet?

So which app does not work? Termux or your Flask thing?

Flask works if there is Internet connection.
I don’t know what is wrong. Maybe, something wrong with phone or net options. But without Internet on some models there is no result if you connect in browser to It just write (in the address line): offline…

Try using the same browser on every phone and see what it does.

I use only chrome

Did you try to access the server from within Termux?
