Have you confirmed that the file you get is actually a tarball?
Sometimes you might get an HTML page and Guix reports the hash for that.

In general it is better to download the tarball manually and then use
“guix hash” on the result after confirming that the tarball is in fact
okay (e.g. by validating signatures or inspecting it).
