FINAL FANTASY XIV 1.22a-Update Error 20524 (An update error has occurred)

Hi,
I cannot look to download the fresh patch, 1.22a, of this game.
I never faced an issue like this one is occurring while I am downloading the patch right time as I did with every old patch.
Each time I download the patch through the auto updater it occurs with this tiny error box in the image which you can see at below any time.
I have attempted some ways to download the fresh patch and every way provided me the similar error message.
I have examined the forums for each and the entire fresh posts of each one having the similar matter and established not anything. So I suppose it is only me who is at this time facing this problem.
The patch could not be downloaded by me, so that is why, I am not able to play the game, and that is not fair.

An update error has occurred.
Error 20524
