I have a very odd issue that recently started happening. When accessing a website with NodeJS service running on port 8080, it will not connect to the service and keep showing an ERR TIMEOUT in the web console. I have tested with other devices on my network (Windows PC / Mobile / Tablet) and they all work fine connecting to the website w/NodeJS service so I know it’s not my network/router…there’s something on my Mac that’s causing this.

Couple weeks ago I tried learning to develop in flutter language and installed the SDK with Visual Studio Code, I am thinking that has something todo with a web emulator running on port 8080 or has changed something in my system settings that’s causing this.

I tried deleting flutter completely but I’m sure something is still lingering because it continues to happen.

UPDATE I also had Android Studio and Docker installed which I removed completely and still have the issue…

Only when I’m on the website and I do a port scan in terminal I see this:

user@MACSN ~ % sudo lsof -n -P | grep :8080
webfilter  2362                  root   18u     IPv4 0x9ef469fd6bf55a1b        0t0                 TCP 192.168.106.98:59260->192.168.0.49:8080 (ESTABLISHED)

I tried to look up the PID (2362) in Activity Monitor but it doesn’t show up…

Does anyone know if the android/flutter web emulators use port 8080 and possibly causing this? If so how can I get this resolved?

Any help/feedback is appreciated.
