Can't open genmon page on the PI #617

Closed jcherney closed 2 years ago

jcherney commented 2 years ago

Expected Behavior

Login and see a genmon web page.

Actual Behavior

No connection according to web browser from 3 different browsers. Fixed IP address can be pinged. I can SSH in with no issues. I'm not that familiar with SSH to go further than reboot or shutdown. Both Xfinity and external programs show the PI online.

Screenshot or Pictures relating to the problem (if possible)

Your Environment

It started acting like this, this morning after the install of 1.18.02. Made a note to check it when I got home. Today we lost power (of course!) and I have no access to genmon. I went outside and pulled the power plug first. It rebooted (I think). I did an SSH reboot also. Nothing changed Weird fact: Wife got the email outage notification at around 4 pm when the power went out- I never did.

Any suggestions would be appreciated, thanks.

jgyates commented 2 years ago

if you power cycled the pi and you can't access the web interface then I would suggest validating your IP address you are using to access the pi via the browser and make sure it matches the ssh IP address.

If you can log in via ssh then you should be able to issue this command:

   cd genmon
   ./startgenmon.sh restart

Note what is displayed on the scene after the above command is entered. Copy and paste that here.

This should restart genmon. You should get an email that genmin is starting. you an also do this from the genmon folder:

   python ClientInterface.py

Then type:

   generator: sendlogfiles
    exit

This will send you log files.

After the python ClientInterface.py I got a genmon not loaded response. to add: I also did an ifconfig and confirmed the IP address.

jgyates commented 2 years ago

Try this 

  cd genmon
  ./genmonmaint.sh -u

Type 'y' for yes to update

   ./startgenmon.sh restart

Then give it a bout 15-30 seconds and see if it is working.

If that does not work type:

   cat /var/log/genmon.log

And paste the last 20 lines here.

still not working. Here are the last bunch of lines:

Now type:

  cat /var/log/myserial.log

and send the last 20 lines.

also, what is the output of this command:

 pip3 show pyserial

jgyates commented 2 years ago

Lets try this:

  ./startgenmon.sh stop
  sudo python3 genmon.py

This command will start genmon.py and only genmon.py. Post the output of the screen here.

If genmon does load you will need to type Ctrl+C to stop it as this will load genmon in the current console context so you can run anything else until you kill genmon with Ctrl+C.

The main thing that changed in V1.18.02 is that genmon now requires exclusive access to the serial port. If some other program is using the port it will fail.

The only thing running on this PI machine is genmon.

jgyates commented 2 years ago

There is the problem.

It looks like The new code I put in is not compatible with older versions of pyserial. I will code a fix for this but in the meantime try this:

   ./genmonmaint.sh -r

wait for it to compete, then type:

    ./startgenmon.sh restart
jcherney commented 2 years ago

I'm back! Thank you so much for your help w this!

I sent a copy of my logs- because I could!

jgyates commented 2 years ago

I got your logs, thanks!

I checked in version 1.18.03 that should fix this if anyone else has issues.
