Mox C ethernet port might be dead


since last week my Turris mox classic no longer work on ethernet port.
I reset all, reinstall with all method and finally erase all data on sd card and install once again.
No method work. With GPIO/USB adaptator i see good boot and shell usage.

I think my mox C is dead. I don’t now how test my mox for fix that.

Should I send an email to support ?
