MCreator 1.8.3 won't install properly and I don't know how to fix the problem

Status
Fixed
Issue description

 

Every time I try to install MCreator it keeps failing.

I've uninstalled and re-installed Minecraft along with Forge and Java but it still won't work.

I've uninstalled and re-installed MCreator multiple times as well but no matter what I get this error.

Can someone who has had experience with this please help me.

Issue comments

The error you provided can be caused by any of these causes:

  • No internet connection
  • Slow internet connection
  • Firewall (on the computer, router or modem) blocking MCreator
  • AV blocking MCreator
  • ISP blocking MCreator or domains it is trying to access

Try to access one of the URLs in the log from the browser. If you can not access these files there too, it is an issue in general, otherwise, you can assume only MCreator got blocked when trying to access these files.

I tried to load into each of the sites via my google chrome browser but I was not able to access the sites.

Do you have a solution to this problem because I turned off everything on my computer that could have been blocking the access to the sites?
