Help LG G3 Marshmallow Update Problem

[LG G3 Marshmallow Problem]

I live in Bulgaria(GMT+2:00),so I recieved the update yesterday on my unlocked LG G3(D-855 a.k.a "the international version").I started downloading it at around like 21:59 on a pretty fast Wi-Fi network(my home network) and now it's stuck at 59%(455.54 of the 769.96MB download)
Are the LG update servers overloded or something?Because even when it was downloading it was as slow as shit....

Now after it had been stuck for 1h or more I just aborted it.But when I go to try to update it again it says "You are using lastest version of current OS" I tried restarting the phone,then back to the update menu...Nothing.I might try to update it via PC...PLS HELP ME ASAP!!!
