Error: Arc api not running about arclight

[MikuMikuMe]

Run the following commands to kill api processes.

pm2 kill
pm2 flush
cd /var/www/html/arclight

pm2 start npm --name "arc"  --log-date-format 'DD-MM HH:mm:ss.SSS' -- start

Thank you. That worked, but I already ran those commands before the certbot.

Hi, it also looks like novnc is not running, I didn't get any output after running netstat -tulpn | grep 6080.

In the vm page it stated VNC Port: 5900, but the console is trying to open port 6080.

Signout and Signin again and see if it works, also u can check out the errors in the noVNC logs. Which version of ubuntu are you using right now?

[MikuMikuMe]

I did try to log out and login again but it didn't work. I am using Ubuntu20.04.4LTS

Sorry for asking this but how to check the logs of novnc?

@Dep0s1t You can check the log files either in the logs section of the dashboard or by going to /var/www/html/arclight/logs. If everything's correct you won't see any errors in the timestamps.

This is what I got. At first it was /usr/bin/env: python: No such file or directory so I created a symlink for it.

According to last line the noVNC process is already in use. Kill the python process tied to noVNC sudo netstat -tulpn | grep 6080 with PID number and signin again.

Sorry for the late reply, I almost forgot about this, I did what you said and after that it's just a blank page for console.

[elondust]

It should be running properly after this. Are you using self-signed certificate for the console, if not then i recommend you to go for the second method by attaching your own domain and encrypt using Let's encrypt.

Also the SSH Terminal and noVNC uses the same configuration path and if there is some mistake after the post-installation configuration, both will throw errors in the logs. Try to post logs here.

[elondust]

I am closing this issue because it has not had recent activity. Also, there's a new patch update available, make sure to update the console to the latest version.
