I'm using the following API call https://badgen.net/github/stars/Athena-OS/athena that actually, when opened by the browser, works correctly. When I insert in the README.md as:
<img src="https://badgen.net/github/stars/Athena-OS/athena">
it returns 
It occurs only on this repository. If I use another one as:
<img src="https://badgen.net/github/stars/Athena-OS/athena-nix">
this different repository works
.
Why is it not working for the public repository https://github.com/Athena-OS/athena ?
