Issue with starting perceptilabs

#1

So i have bee trying to make perceptilabs on my laptop for about a day now.
I’m just dipping my toes in this software.
I tried to run it with the installation instructions, on the getting started page.

The problem is that i get an openPLC login page in the start without a sign in option.
I am not able to create an account in the lab. Is there a way to fix this ?

this is the initial output, i think the program is running for sure. Its just the screen thats stopping me from going ahead.

Hi @cpreet,
Welcome to the forum!

It looks like you may have another service (like OpenPLC) already running on port 8080.
You can run this before you start PerceptiLabs to ensure that no ports are blocked:
netstat -a -n -o | find "8080"
netstat -a -n -o | find "8000"
netstat -a -n -o | find "8011"
netstat -a -n -o | find "5000"
If any of them return something, you want to kill that service before starting PerceptiLabs.

Hope that helps!
All the best,
Robert

Yes, I thought i had removed that software from my system. Turns out, it has been in the autostar menu from the time i had first installed it, even after a regular cleanup. Time for a reinstall. Anyway what worked was

systemctl stop openplc
systemctl disable openplc

Started perceptilabs after this and it worked as intended.

Thanks for solving. :smile:
