Janus problem.

[pikkaroni]

I have an issue running the raztot app after succesful install. I get stuck here, and Janus reports errors, I hope someone can spot my mistake, i'm quite new to linux:

I followed and sat up everything according to the guide, but it does not seem that i can open the Raztot webapp even though my Dataplicity server link is working fine. I have also tried to run the app locally, but with same result. Hopefully it's ok to ask this here, also new to github :)

All of the warnings in the log you posted are actually normal for Janus -- none of them should have any impact on the raztot app itself. It looks like the app started successfully based on the Running SocketIO app on 127.0.0.1 message.

Can you clarify what you mean by the Dataplicity server link working? Do you see the login page for the raztot when you go to that link? Or does it show a 502 Gateway Error message? Alternatively, it could be showing a penguin page, which means that nginx isn't running.

Can you also paste the output of sudo systemctl status nginx.service?

[pikkaroni]

This is my Dataplicity page after i enter the Raspberry Pi remotely:

So maybe it is nginx that isnt running then, but from the terminal it seems like it is active:

How do I proceed? it is a 3 b+ board, if that makes any difference.

Edit: I can log in to the Pi through Dataplicity just fine with su pi and then my password, and it seems the app is running just fine, am I missing how to open the app interface somehow? Or should it open automatically after cd ~/raztot source run.sh local ?

[benbusby]

Looks like nginx is working fine from the output you included.

If you open the url on the Dataplicity page in your screenshot (in the right side column, the one that is obscured), do you see any errors or results? That’s where the raztot web app should appear.

I have now managed to start the stream, and I can move the wheels, but no camera feed. I can capture a video and play it though. Why is there no live feed?

This is the readout:

Hope you can help.

Hmm, well nothing in the console output indicates any error with the live stream. Can you open the web dev tools (Ctrl+Shift+I on Chrome) and tell me if you see any errors under the “Console” tab after you hit Start Stream?

[pikkaroni]

I did get an error from Janus it seems. Im tempted to restore raspbian and do a fresh install.

Here is the google chrome console error:

Cannot share error log it seems, here is a screencap:

[pikkaroni]

I am reinstalling Raspbian and now installing the app on a fresh system, I am suspecting some problems due to a motion server I had set up earlier. Will update and close if I dont encounter any more errors.

[pikkaroni]

A complete reinstall of raspbian and Raztot worked, I think maybe motion or noip-2 was interfering with the stream. Thank you for the support.
