I couldn’t open any web-pages and received the error message

Hi guys,
I was doing research on my computer yesterday, but I couldn’t open any web-pages and received the error message below.
I checked my internet configuration and rechecked if the cable was in place but nothing was abnormal.
I have also tried to scan the computer for viruses but nothing came-up.
What is error 12029?
