Unable to join network queue "LAN" with address auto (Windows, SO_REUSEPORT error)

Continuous Print API Error 500 when clicking "start managing button" for continuous print plugin, G code file is added on the job queue.

This is not as expected, since the printer should start loading the job and print.

Thanks for the sysinfo bundle - I just took a look at the logs and it appears to be an issue with port discovery:

Traceback (most recent call last):

AttributeError: module 'socket' has no attribute 'SO_REUSEPORT'

Apparently SO_REUSEPORT exists on Linux, but not on Windows - more detail here. As I mainly use Linux, I didn't notice this compatibility issue. I'll start on a fix, but it'll take a little bit to publish due to some other changes in the pipe.

In the meantime - if you can get to the Settings page, try going to Continuous Print > Queues and removing the entry marked LAN, then restarting OctoPrint. This should remove the initial connection logic and make it work locally for you at least.

Where can i get bed clear G code for creality Ender 5, to use the extruder head to knock the print off the bed? i go not fin any example codes in the gcode script section?

Glad to hear it's working for you!

Unfortunately I only have gcode scripts that users have contributed (beyond the ones for my own printer models). If you're comfortable trying to make your own, maybe start by modifying the "Sweep Gantry" script example. I'd appreciate your contribution for anything you find works well with a stock Ender 5 :)

v2.3.0 will surface this error but make it so you can at least use the queue - I'm leaving the bug open until I fix the root cause.
