Ok, I think I replicated your issue.
You will need to use a vpn. Then that will allow you to open the official Sports Fire site to download and install.
Also, I just now downloaded the Sports Fire apk from a 3rd party site, Softonics, using Downloader without a VPN. It downloaded and installed without issue. All channels played properly.
So, you can get it using a 3rd party site without a vpn or use a vpn and get it from the official Sports Fire site.
Imho, I would get a vpn. Especially for sites such as this. There are plenty of free VPNs available.
