Failed to download the third-party software: MinGW 6.3.0 from MinGW-w64.org

I am trying to download this third party software for MATLAB R2020b but the installation keeps failing at the second step (the part where its downloading the third party package).

I have tried reinstalling MATLAB multiple times but the error kept persisting.

My log file is attached below:

Hi,

Please try the following steps to resolve this issue.

1. Download MinGW 6.3:

https://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win64/Personal%20Builds/mingw-builds/6.3.0/threads-posix/seh/x86_64-6.3.0-release-posix-seh-rt_v5-rev2.7z

2. Extract the ZIP-file in an empty directory. Ensure that there are no spaces in the path, for example: C:\MinGW-64

3. Please create the environment variable MW_MINGW64_LOC like you can find here: http://www.mathworks.com/matlabcentral/answers/223482), which points to the path mentioned in 2, for example:

MW_MINGW64_LOC=C:\MinGW-64

4. Please restart MATLAB and then call 'mex -setup' in MATLAB in order to check and configure MinGW. The output should show something like: "MEX configured to use 'MinGW64 Compiler (C)'...".

Hope this helps.
