The font seems not to exist (anymore?) under that URL:

https://db.onlinewebfonts.com/c/77e2c172ad2201a53a7462c14893bb10?family=Conthrax

Generally, the use of onlinewebfonts.com is not recommended. It is considered unreliable and very often causes loading issues and lags due to unavailability.

You could try this source instead:

https://www.cdnfonts.com/conthrax.font

@import url('https://fonts.cdnfonts.com/css/conthrax');

Alternatively, download the font somewhere, convert it to .woff2 if you don't find it in that format, then upload it locally on your wiki. You may have to ask to activate font upload with Fandom support first. Hosting the font locally is the best solution as it doesn't depend on external services.

I apologize! I'll take note of that in the future and add the site link. Thank you for correcting me and responding to my post.

I'll try that source instead, first. But I also reached out with Fandom support to allow me to upload files in .woff2 format. I think you're right that this is the best solution so that this doesn't happen again.
