Critical - UPS: In bypass in response to an internal hardware fault.
Then one second later

Informational - UPS: Return from bypass, internal hardware fault no longer present.
Random times in the day.
I am curious is the firmware upgrade you mentioned is of the UPS itself or the network card?
If it is the latter, I would suggest trying a downgrade and check if the fault still appears.
Just to identify if the issue is rooted in malfunctioning hardware or a software issue.
You can find the 2.0 version of the firmware here:
I would suggest using the FTP or SCP process for the downgrade, as detailed in this document.
If the issue is still present after the downgrade, I would advice getting the support file from the network card and contact your local customer care center.

Downgrading the AP9640 network card from 18.104.22.168 to 22.214.171.124 fixed the issue.
