WLANPi Pro GUI Error - COCKPIT 502 Bad Gateway

[jmack778]

Still receiving this error from the GUI when attempting to login to the Cockpit tab. I am SSH'd into the WLANPi now but not sure what command to run to update the IOS?

[jmack778]

wlanpi@mackeypi-53~ $ sudo apt update Commands - 9-23-24.txt

There are no references to cockpit in this output.

Is the service running? Try systemctl status cockpit from SSH.

What is the output of journalctl -u cockpit?

Active: inactive (dead)
TriggeredBy: ● cockpit.socket

Is normal until the first time you browse to cockpit which should activate the service.

This looks like an issue with the self signed certificate. Did you try removing and reinstalling?

sudo apt remove cockpit
sudo apt install cockpit

[jmack778]

No, but I just did now and still get the same error on the GUI when attempting to access Cockpit.

Ah, I'm sorry. I completely forgot all about how we were handling the self signed certificates. The wlanpi-webui package handles creation of them.

Let's try this. Please remove our self signed cert, reinstall the wlanpi-webui, and restart the WLAN Pi.

sudo rm /etc/cockpit/ws-certs.d/0-self-signed-wlanpi*
sudo apt remove wlanpi-webui
sudo apt install wlanpi-webui
