i wanna run flutter web app on chrome in debug mode but whenever i try so, i get this error

Failed to establish connection with the application instance in Chrome. This can happen if the websocket connection used by the web tooling is unable to correctly establish a connection, for example due to a firewall.

but release mode works properly using

flutter run -d chrome --release

i have tried;

flutter clean.

flutter pub cache repair

switching to master channel

disabling firewalls

But none of these worked. I seriously need to run the app in debug mode for troubleshooting. Thanks in advance

You have to download Dart Debug Extension on Google Chrome to run flutter app on chrome through your editor

None of the above worked for me, too. Then, I disconnected my VPN and started debugging. It worked fine.

This error kept popping up randomly. I would run flutter clean but that only worked for a few runs then the problem came back. I decided to use Edge and so far I haven't seen the problem again.

flutter run -d edge
