Get 403 Forbidden after upgrading Mycodo to latest version

[donplumpos]

• Mycodo Version: 8.16.2
• Raspberry Pi Version: 4B
• Raspbian OS Version: Bullseye

My latest Mycodo version was 8.15.13, then i tried an update (with Python Version 3.9.2).
After restart i tried to connect via Browser and get 403 Forbidden.

I checked /var/log/mycodo/mycodo.log and got:

I followed the instructions to delete and recreate the Database under https://github.com/kizniche/Mycodo/wiki/Deleting-and-Recreating-the-InfluxDB

But when i restarted the Daemon with sudo /var/mycodo-root/env/bin/python /var/mycodo-root/mycodo/mycodo_daemon.py --debug
i got the same lock error on the database:

Restore completed successfully without errors.

Then i tried to connect with browser to the dashboard but got:

Error 502: Bad Gateway Error

Something bad happened but it's probably not your fault. Try refreshing the page to see if it will load. If that doesn't work, try rebooting your system, then try refreshing it again. If that still doesn't work, submit a [new issue on GitHub](https://github.com/kizniche/Mycodo/issues/new?template=problem-bug-report.md) with any useful information that can help determine the cause of this issue.

The last 50 lines from the Mycodo frontend web log can be viewed with the command:

journalctl -u mycodoflask | tail -n 50

If you create an issue on GitHub, provide this excerpt of the log for diagnostic purposes.

With journalctl -u mycodoflask | tail -n 50 i got:

(Background on this error at: https://sqlalche.me/e/20/e3q8)
Could not read the Mycodo database. Please submit a New Issue at https://github.com/kizniche/Mycodo/issues/new
NoneType: None

I am getting this same error on a new install. I can see that the permissions on /opt/Mycodo are restricted to only the root user after the installation and if I change those permissions, then I get past the 403 Forbidden error and then get the 502 Bad Gateway error. Have you checked the permissions on your folder to see if that is what is the cause of your database file being inaccessible?

[kizniche]

Can you attempt to run the frontend with the below command and see what error it produces?

cd /opt/Mycodo/mycodo
/opt/Mycodo/env/bin/python -m gunicorn \
--workers 1 \
--worker-class gthread \
--threads 2 \
--timeout 300 \
--pid /var/run/mycodoflask.pid \
--bind unix:/usr/local/mycodoflask.sock start_flask_ui:app

[kizniche]

You can also try this command to attempt to upgrade the database. Having the full log output would be helpful. Please attach as a text file rather than pasting it, though.

sudo /opt/Mycodo/mycodo/scripts/upgrade_post.sh

[donplumpos]

Your first command to start the frontend crashed with error, see attached frontend.log.
Your second command to upgrade the database has also errors, see attached mycodo.log
