MFIX can not be installed

I have been experiencing a HTTP error while installing FIX-21.4.

I tried other versions (22.1 &22.1.1)and changed two different computers, but this error still happened.

This looks like either a local network problem on your side, or a temporary problem at Please try again and let us know if it’s still a problem.

I am having the same issue, the HTTP error.

I just tried it (two different computers and networks) and it still doesn’t work. I’m sure it’s not the network or the firewall.
