Highlights shows 404 screens for my own website. How to debug?

Anyhow, I have a website and I recently moved it to a new server I'm managing myself. Since then, when it shows in Highlights (Éléments clés) on my firefox home page, it shows the Server's 404 page. It baffles me that it's not even WordPress' 404 page -- normal users sees a branded 404 page when they hit one. This one is VestaCP's.

I was wondering how I could start debugging this. I attached a picture of what I mean below.

Cheers, Karine.

Sometimes this type of problem is a certificate issue, or your protection programs.

The website is https://www.lessence-ciel.com. It goes through Cloudflare, but so do all my other sites. I have a development environment at dev.lessence-ciel.com too but it serves a password page if you go. It still only shows as a 404 from the firefox highlights, though. IIRC (it's been a couple months...), before we moved the sites, it used to show the password screen.

The biggest difference between this site and the others I manage is that this one is on a VestaCP server, which is what serves that very specific 404 screen. It must be a server issue, I just don't know what to look for and I figured if I could debug how Firefox does its "screenshots" it'd point me into the right direction.

I had no problem with; https://www.lessence-ciel.com Note: switching to English does not translate the whole page.

Did you check out my post that said: There is security software like

The website isn't translated as a whole presently ahaha

And yes the website works. I know that. This isn't the problem.

I fail to see how what you suggested was relevant to my problem, and this is strengthened by your last response just checking whether the site works or not. It does work. My question is related to the firefox highlights: why is it showing a server 404? What is Firefox, as a browser, is doing, to be "prevented" by my server to pull images for its highlights?
