Frigate: Port '8555' is already in use

1

I installed the Frigate (Full Access) Add-on and created a basic frigate.yml file. When I start Frigate, I get

Failed to start add-on

Port '8555' is already in use by something else on the host.

I am not that good with shell commands, but was not able to find any process listening on this port.

Does anyone have suggestions on how I can find the process that is using this port?

Appreciate any help.

Thanks.

It would be helpful for the community if you post the basic frigate.yml you created here.

Anyway, to see what service is using port 8555 on your system run from CLI:

sudo lsof -i:8555

or to see what ports are in open/listening state run:

sudo lsof -i -P -n | grep LISTEN

Thank you @Tamsy.

sudo lsof -i:8555 returns about 50 lines.

sudo lsof -i:8555 | grep 8555 returns nothing.

sudo lsof -i -P -n | grep LISTEN returns nothing.

To me, it looks like the operating system thinks that there are no processes listening on port 8555 but Frigate does. Hence my confusion.

The content of frigate.yml is:

mqtt:
  host: !secret mqqt_host
  port: !secret mqtt_port
  topic_prefix: frigate
  client_id: frigate
  user: !secret mqtt_user
  password: !secret mqtt_password
  stats_interval: 60

detectors:
  coral:
    type: edgetpu
    device: usb

Check the Frigate logs for errors.

Maybe you want to change WebRTC from default port 8555 (TCP & UDP) to port 8554.

Here is how I configured WebRTC through the Frigate Add-on configuration page:

That did the trick. I also got the port in use error with 8554 so I am using 8553 and everything is working. Thank you for your help with this, @Tamsy .
