I have an issue with my Minecraft launcher - I downloaded modpack for minecraft then the launcher started an update for the modpack version which it's 1.6.2, however then I started to get the issue

[15:40:59 ERROR]: Gave up trying to download https://libraries.minecraft.net/net/sf/jopt-simple/jopt-simple/4.5/jopt-simple-4.5.jar for job 'Version & Libraries'

[15:40:59 ERROR]: Job 'Version & Libraries' finished with 26 failure(s)! (took 0:01:06.362)

At the same time I had just downloaded Avira antivirus and ran it, but unfortunately removing it and trying again didn't help. I've tried to restore the system to the point before downloading the antvirus and the mod pack a 2 days ago, I've tried turning off the firewall and I have tried removing the whole .minecraft folder all with no luck at all. I can't figure it out, all the servers are working and I have good internet connection but some of the files download fine and other don't.

The full log is here:

    It looks like a firewall or something is preventing Minecraft from connecting to the internet.

  • It doesn't look like this is Minecraft's fault; if its a firewall, that's something on your computer or network that's causing the issue.

    Have you tried downloading the file from that link you posted: libraries.minecraft.net/net/sf/jopt-simple/jopt-simple/4.5/… - if you can't download the file from a web browser, Minecraft will also be unable to download it, you'll need to resolve your network problem first.

The issue was that DNS I used, so I used Google's public DNS, which is free, safe and fast. You can use Google DNS here, and get troubleshooting help from here.

  • where do I specify the DNS server for minecraft?

  • @Mike DNS settings are changed computer-wide by going to your network adapter's properties.
