Canaan Avalon A1066 Pro 55TH not displaying fan speed or temp

I have a Canaan Avalon A1066 Pro 55TH, but it’s not showing the fan speed or the overall temperature of the unit. This issue popped up after I updated to the latest firmware.

Would you mind to try to reset the unit to factory default? To reset the miner to factory default look for "func" button and hold it for 5 to 15 seconds then release then check it again. If still doesn't work and you can still access the unit through the browser try to copy the Cgminer API logs and paste it here make sure you use Code Tag to make your post clean or paste the logs in pastebin.com and paste the link here.
