DRC error means Design Rule check related error sorry but I am using protues 8 but I think power pins nets are by default is VCC/VDD so you need to change the net name which you using for pin 31 which is #00025 so change the net name of your pin 40 to #00025 that solve your problem.

To change name you can go in schematic and click controller go in properties and click on hidden pins you see there pin 40 named as VCC changed it to #00025 then no error would be their.

you can do by changing the net class in power rail configuration as shown in attached image

Other way is to do name your 7805 output pin 3 as power rail VCC so no need to change the power rail net class do any of this will solve your problem
