The plugin needs to get the M503 response from the firmware in order to read the settings. If you're getting nothing out of this, then the firmware needs fixing to provide this output. If host keepalive is preventing this from being sent, it needs to be fixed.

The host keepalive feature seems likely to be a red herring (or some special bug triggered with this) - since every test that you've performed since it was broken worked, you should do one more test enabling only this again to make sure it definitely breaks.
