How to solve TLS handshake failed error?

Question

I was trying to install sublime text on my ubuntu 18.04. The method I tried to install Sublime Text is to follow this link Linux Package Manager Repositories but it throws below error when I issue the apt update

Err:8 https://download.sublimetext.com apt/stable/ Release                     
  Could not handshake: An unexpected TLS packet was received. [IP: 136.17.0.7 83]

I don't think this related with proxy setup correct me if I'm wrong. I just checked with upgrade my git to latest. I added ppa and issued apt update and it installed latest version. So now my question is why this not work with Sublime Text?

Note: I'm using this machine behind corporate proxy and I will provide more information if you need anything. I searched online and end up nothing.

@karel My apt.conf.d/01proxy configuration is right. In fact I tried to update the git using the ppa method and that was working fine. Now my question is why not this work with sublime? — Raja Simon, Nov 20 '18 at 09:53
Sublime text editor is a native Ubuntu snap package in all currently supported versions of Ubuntu. You can install Sublime text editor 3 from Ubuntu Software now instead of using the ppa method, and then Sublime text editor will receive updates automatically. — karel, Nov 20 '18 at 09:56
Is that mean I can install it from Ubuntu Software Centre? I searched and it returned nothing. — Raja Simon, Nov 20 '18 at 10:10
Open the terminal and type: sudo snap install sublime-text --classic — karel, Nov 20 '18 at 10:11
