I recently came across this error

Hello guy 
I recently came across this error while I was updating my apps. It said, "fix unable to download patch files".. All I was able to conclude was for the particular file that I was downloading, they couldn't get the patch files. Correct me if I am wrong and also help me to get a fix for this. I checked my settings and everything but nothing worked. Please help me out with this issue. 
Thanks in advance.
