Adb Cannot Connect to Daemon At Tcp:5037

error: cannot connect to daemon at tcp:5037

Android Studio error: cannot connect to daemon

I solved the problem on my own.

Out of frustration I opened Control Panel > System and security > Windows defender firewall > Allowed applications and I added adb.exe (both private and public networks).

I came back to Android Studio, ran the app and magically it managed to initialize ADB and my phone connected via USB was there.

I don't really know why this worked, since when I checked in Start > All Programs > Accessories > System Tools > Resource Monitor > Network > Listening Port it said that on port 5037 the firewall was allowed.

Moreover I don't know why up to a week ago all worked fine and now I had to do this process to make it work.

If someone more experienced manages to explain this behaviour better I'll update this answer (or accepts his as best answer)

Emulator: emulator: ERROR: AdbHostServer.cpp:102: Unable to connect to adb daemon on port: 5037

This is likely caused by insufficient permissions. Run Android Studio or your command prompt (whichever you prefer) as an administrator and that should solve your problem.
