I am getting the following error when I try to invoke a REST API with dart HTTP module, this happens only on iOS Simulator, tried running the same code on an iOS Device and Android Emulator, working fine on both of them.
This is what I am getting when I log the exception,

Tried to access my API URL with Safari on Simulator and it is working fine too, apart from the flutter exception, I am not getting any other information/logs.
The reason for my issue has to do something with Sophos Antivirus, I have removed Sophos and was able to solve the issue. I was getting a similar socket exception when I try to use flutter pub get, but only with one of my internet connections, it is working fine when I switch to another connection, I tried to get flutter pub get working by removing the Sophos, and it solves both flutter pub get issue and the connection issue with the iOS simulator.
