Favicon head-meta

Hello.

I have a website and all pages except the one have a favicon. I am running hugo for that specific page. I wanted to have a favicon on that webpage as well.

So, I added <link href="https://blabla_favicon-png.png" rel="icon" type="image/x-icon"> to…/layouts/partials/head-meta.html. Please look at the attached screenshots.
It is the same link as on other pages but I did one change: I had rel="shortcut icon" but in the case of this particular page I added rel="icon"

When I save it and run it from my localhost the favicon shows in Chrome. When I merged it to GitHub, Chrome provide information about a 404 error.

What can I do?

In favicon.ico is throwing a 404 · Issue #711 · gridsome/gridsome · GitHub I found that I can add <link rel="icon” href=“data:,”>
Where can I add it if it is a relevant solution?

Thank you.

Best regards,
AA
