Session stops supposedly because of a change in the ip address

[ndonkoHenri]

Description
After a certain amount of time, my session gets disconnected and an error message is showed up.
The error message is very descriptive and clearly says that my ip address has changed from x.x.x.x to z.z.z.z. Surely because I went offline for a while and came back a few moments back online(hence was assigned a different ip).
When I first saw this error and reported on discord,@FeodorFitsner responded saying: 'Could be that client IP changed. It's mixed into encrypted string.'

How to reproduce the issue:
I think this particular issue will happen for all Flet-made applications. But for this issue you can use this url:

• Open flet-colors-browser.fly.dev this,
• allow the session running(open)
• go offline for a while and come back online, ensuring your ip changes! Verify your ip before and after here.
• open back your browser to this same app session, and you hopefully should see the error.

Describe the results you received:
This is on Windows PC as PWA.

This is on iPhone X as PWA.

Describe the results you expected:
I expected it to not show this error, and perform like a normal website...

Additional information you deem important:
This issue happens occasionally. And refreshing did not solve the problem(surely because refreshing a page can't bring back the old ip to life).
We are then oblige to (close that existing session and) open a new session inorder to continue our stuffs.

Flet version (pip show flet):

The app uses the latest flet version.

Operating system:

I had this error on my iPhone and windows PC.
