also something to note that i can install old forge versions (i tried 1.12.2 and it worked normally no errors), and for some reason my pc doesn't recognize that java is not on it? (jarfix doesn't recognize it is on my pc) this is also after several reinstalls of Java
I also tried to install forge using Curseforge it goes on then says it failed.

In order to root out one of the more common issues, we'll need to see your hosts file. Here's the steps to getting this file.

1) Press the Win + R key on your keyboard.

2) Paste the following into the prompt that opens: notepad %windir%\system32\drivers\etc\hosts

3) Use Ctrl+A to select everything in the file, then Ctrl+C into the textbox to post to this thread.

# Copyright (c) 1993-2009 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
#      102.54.94.97     rhino.acme.com          # source server
#       38.25.63.10     x.acme.com              # x client host

# localhost name resolution is handled within DNS itself.

Remove the libraries.minecraft.net line and then try to do so again.

[AmGeD]

still the same error

[ChampionAsh5357]

Hmm, my only other guess would have to do with differing direction traffic for ipv4 and ipv6. However, that should only occur during the game load, and this is in the installer. Just to confirm, you removed the line from the hosts file and saved it and retried the installer? Would you mind making sure you've loaded the vanilla version at least once and restarted your computer? I doubt this will fix the issue, but it never hurts to try.

[AmGeD]

made sure the line is removed from hosts, confirmed the game version is installed and played it vanilla, restarted my pc, still no luck

[ChampionAsh5357]

Strange, would you try using a VPN and see if that fixes the connection? You could try updating the Java version as well, but that should not do anything as the installer works with Java 8 fine.

[AmGeD]

sorry for the delay my mointor had issues, i tried using Psiphon 3 and retried installing still no luck, i also have the latest version of java installed on my pc

[AmGeD]

 

looks like i am not the only one having this problem

[ChampionAsh5357]

Just to make sure, did you configure anything in your ipv4 or ipv6 settings when I mentioned it? I want to make sure traffic is only from ipv4 in both directions or ipv6 in both directions. You should be able to disable ipv6 through your machine or router.

[AmGeD]

this worked! i went to my Network Adapter options and unchecked the ipv6 box and everything installed fine my ipv4 options were default).
