Unplugging and replugging the ethernet cable brought it back.

My Duet2 ethernet DWC lost connection while printing.
Refreshing the page in chrome results in: This site can’t be reached jubilee.lan refused to connect.
Can still ping and telnet.
Duet and telnet both giving a lot of: Warning: Driver 1 warning: over temperature warning
The driver warning stopped when print finished, but chrome still can't connect.
I also issued a M122 from telnet see below.
MCU temperature maxed at 47.0

Anything I should try before rebooting it?
What does Error status: 0x14 mean?

Thanks

M122 via telnet, after print complete:
