Can you open that URL http://192... in the browser on your phone?

[imrrobat]

[FeodorFitsner]

I mean can you open http://192.168.56.1:8551/my-app/main-py in the browser?

Check your laptop IP address and confirm if it is same like the link provided by flet. If not the same, replace the one in the link by your correct IP and try again.

[imrrobat]

no.. :(

I have got the same issue before and @ndonkoHenri helped me to solve it. It was related to my real local IP address which was not the same like the link provided

Did you check you IP and compare?

i read this article and yet it didn't work for me... i hot spot my internet from phone to pc. can this cause of problem?

[DavMelchi]

Just try now with my phone as hotspot and it works.
I try with another 2nd phone connected to the same hotspot created with the 1st phone and it was a success also.

• link provider by flet qr scan : https://android.flet.dev/192.168.112.1%3A8551/flet_pretest/test_flet-py
• my laptop ip adress : 192.168.67.143
• final link that I used : https://android.flet.dev/192.168.67.143%3A8551/flet_pretest/test_flet-py

Don't forget to change status of your network to private also as indicated in the article

I got the same problem too.
After I checked, it turned out that the IP given by flet was the IP of the WSL, not the IP of the host being used.

So, to solve this problem I did:

• I added the project manually by changing the IP to host IP
• Changed the network from "Public" to "Private"
• Because I have an active firewall, so I open firewall on spesific port. For example port 8000, so every time I want to run the flet application, I always use port 8000.

[imrrobat]

now i copy my real IP address and put the network on private. and this is a new Error :D

[DavMelchi]

Copy paste this link in the browser you will have a button to open flet directly. It is the link above the qrcode which does not contain android.flet.dev you can add directly manually in flet.

[imrrobat]

it still didn't work 😭

How if the link is: http://192.168.x.x:8000/my-app/main-py (use http instead of https).

Make sure you have run the app in port 8000 and allow the firewall.
