Unable to access Web interface

I’m having the same problem of

This site can’t be reached
192.168.1.242 refused to connect.
ERR_CONNECTION_REFUSED

IP is good. I can access the Raspberry Pi via SSH.

Flightaware’s website is showing that my feeder is active and sending info.
I used to be able to access the web interface.

Tried:
sudo piaware-status
PiAware master process (piaware) is running with pid 3828.
PiAware ADS-B client (faup1090) is running with pid 4144.
PiAware mlat client (fa-mlat-client) is running with pid 3867.
Local ADS-B receiver (dump1090-fa) is running with pid 4129.

dump1090-fa (pid 4129) is listening for connections on port 30005.
faup1090 is connected to the ADS-B receiver.
piaware is connected to FlightAware.

dump1090 is producing data on localhost:30005.

Your feeder ID is (my feeder id)___ (from /var/cache/piaware/feeder_id)

Tried
:8080/
:80/
/
/dump1090-fa/

All of these gave the same error that it can’t be reached.

I’ve tried restarted PiAware and the Raspberry Pi. Tried upgrading PiAware and dump as well. Still getting the error.

(I have FlightRadar24 too, and it’s working fine on the same Pi. Both software have worked together on the same Pi with no issue. I can access the web interface of the FlightRadar.)
