Web Interface not working #389

Closed Rodrix33333 closed 1 year ago

Rodrix33333 commented 1 year ago

I am now trying with the second and last Raspberry Pi Zero WH that I have. I am trying to setup all the software part before I continue with the wiring which I haven't figured out yet (separate issue).

I cannot get the web interface working.

Steps I did:

  1. I flashed the SD with the latest 1.3 image.
  2. The Raspberry Pi boots successfully and shows the menu.
  3. I created the wpa_supplicant.conf and ssh files and put my wifi network
  4. I was able to successfully find the Raspberry Pi at 192.168.0.8
  5. I SSH'ed into it using pi@192.168.0.8 using password raspberry, SUCCESFULLY.
  6. I attempt going to the Chrome browser to http://192.168.0.8/ and nothing happens (Connection rejected)
  7. I go back to SSH and type "sudo raspi-config". I enable SPI. I run "sudo reboot".
  8. I attempt going to the Chrome browser to http://192.168.0.8/ and nothing happens (Connection rejected)
  9. I try to change the port to "80". sudo python3 /home/Piano-LED-Visualizer/visualizer.py --port 80
  10. I attempt going to the Chrome browser to http://192.168.0.8/ and nothing happens (Connection rejected)
  11. I cd to /home/Piano-LED-Visualizer and run "sudo -E /usr/bin/python3 visualizer.py". The console never returns anything like if it is running something.
  12. I attempt going to the Chrome browser to http://192.168.0.8/ and nothing happens (Connection rejected)
  13. Control+C to stop the console... and I am stuck. I have no idea how to proceed. I have tried everything in my reach...
  14. I run "sudo python3 /home/Piano-LED-Visualizer/visualizer.py &" (this time with a & at the end) and I get as a result [1] 552. I try again and the numbers start to change. I have no idea what this means.
  15. I attempt going to the Chrome browser to http://192.168.0.8/ and nothing happens (Connection rejected)
  16. I run " sudo python3 /home/Piano-LED-Visualizer/visualizer.py --webinterface true"
  17. I attempt going to the Chrome browser to http://192.168.0.8/ and nothing happens (Connection rejected)

I cannot think of anything else to test. You can see that I don't want to bother you or take your time, but I have no idea how to proceed...

Please help :.(

P.S: Trust me, I am not "lazy". I have read all the 46 issues and every single comment. I have also watched all of the following videos and read every single Youtube comment. I just cannot get this to work and I am getting desperate. I hope you can help :/ https://www.youtube.com/watch?v=IZgYViHcXdM https://www.youtube.com/watch?v=31xEZO2boNs https://www.youtube.com/watch?v=lbLjS3s74fU https://www.youtube.com/watch?v=s8uX3LVx21E

I flashed the SD with the latest 1.3 image.

The latest is 1.4 which uses services as a method to run Visualizer. You run it with

sudo service visualizer start (restart/stop)

You can stop the service and then run Visualizer with standard sudo python3 /home/Piano-LED-Visualizer/visualizer.py command to see console output and errors.

Rodrix33333 commented 1 year ago

Thanks a ton!

Should I update the code via GitHub or is there a link to the 1.4 image? (If so can you provide me the link to the image? I cannot find it).

Then I should do: sudo service visualizer stop sudo python3 /home/Piano-LED-Visualizer/visualizer.py

Correct?

If I connect to SSH to IP 192.168.0.8, will the url to visit the web console be http://192.168.0.8/?

Thanks so much for your help!!! :)

https://github.com/onlaj/Piano-LED-Visualizer/releases/tag/v1.4

Then I should do: sudo service visualizer stop sudo python3 /home/Piano-LED-Visualizer/visualizer.py

Correct?

Yep

Rodrix33333 commented 1 year ago

You are the best! I will test and report asap.

If I connect to SSH to IP 192.168.0.8, will the url to visit the web console be http://192.168.0.8/?

Will the IP be the same?

onlaj commented 1 year ago

Yes, unless you specified other port. It should show an error if default 80 is already taken by some other app.

Rodrix33333 commented 1 year ago

Update: Installing v1.4 with BalenaEtcher results in blank screen on LCD. I tired with two SD cards. (Even waited 15-20 minutes and still blank) Reverting to original SD card with v1.3 results in correct loading of menu on LCD. System boots in about 2-3 minutes.

How should I proceed?

Rodrix33333 commented 1 year ago

Any commands I can run on v1.3?

At least that one is able to boot successfully and I can access SSH.

onlaj commented 1 year ago

Try to kill all python processes:

sudo pkill python3

and then launch visualizer with

sudo python3 /home/Piano-LED-Visualizer/visualizer.py

Rodrix33333 commented 1 year ago

Thanks.

I am on a new fresh install of v1.3. I run that and I got:

Inport set to rtpmidi raspberrypi:Network 128:0 playport set to rtpmidi raspberrypi:Network 128:0

It does not output anything more and command does not end.

http://192.168.0.8/ still gives ERR_CONNECTION_REFUSED.

Suggestions? Thank you

onlaj commented 1 year ago

Is there no message about webinterface starting? It seems that it doesn't load at all. Do you still have sd card with version 1.4? Try to load it, SSH into RPi and type sudo service visualizer stop and then, just to be sure sudo pkill python3

then launch visualizer sudo python3 /home/Piano-LED-Visualizer/visualizer.py

Rodrix33333 commented 1 year ago

No there is no additional message, nor any message about webinterface starting.

The v1.4 does not boot at all. Blank screen.

Suggestions?

onlaj commented 1 year ago

The v1.4 does not boot at all. Blank screen.

If the Visualizer script didn't start it will be blank, but it doesn't mean that you can't SSH into RPi.

Rodrix33333 commented 1 year ago

No luck :/

If I put in the SD with v1.4 I cannot even login to SSH.

onlaj commented 1 year ago

That's weird. Did you configure wifi connection through the wpa_supplicant file?

Rodrix33333 commented 1 year ago

I re-did the whole procedure again with 1.4.

We are getting somewhere... image

Finally! I see the web interface. So I guess I have to manually launch the sudo python3 /home/Piano-LED-Visualizer/visualizer.py every time?

onlaj commented 1 year ago

I'm not sure yet. The reason I switched the boot process to service is because some users had problems with old method, which was cron. It was launching the script before RPi connected to the internet. With service method it waits for internet, but maybe something else is blocking the script.

You can try to add delay by editing it with sudo nano /lib/systemd/system/visualizer.service

and then under [Service] and before ExecStart=sudo python3 /home/Piano-LED-Visualizer/visualizer.py add ExecStartPre=/bin/sleep 30

Rodrix33333 commented 1 year ago

Thanks so much! :) For others, here is the summary:

Do this everytime you turn on the device.
