I have designed a PCB using Autodesk Eagle.

After I routing the PC and check for errors from Tools -> Errors, there are lot of airwires (31) like below. But, I couldn't find any airwire.

How to solve this problem?

    \$\begingroup\$ Try the hints given here: rerun DRC, set the airwire colour to bright magenta, turn all layers off except the airwire layers \$\endgroup\$ – Huisman Dec 17 '19 at 7:16

After rerunning DRC problem is solved as @Huisman mentioned.

If you just select Tools -> Errors, It shows previous errors without updating current status.

Use Tools -> DRC... and click on the Check button to update the errors.
