My website icon still displays Vercel and also got SSL/TLS certificate error

Hi, my site name is
and ID site : 5a0df6a4-dfe5-4c6e-a184-9ea1b1135f8b
my custom domain :

First problem : Currently, my website’s icon that show on google search still display Vercel’s icon rather than show mine (At the first time, I deployed my site to Netlify, then I went to Vercel and finally back to Netlify )

Second problem : I don’t know whether it is called the problem or not but when went from Vercel to Netify the list of the site in my account doesn’t show the image of my site like it used to be.

Last problem : when I went back to Netlify I got this error " doesn’t appear to be served by Netlify We can’t renew your Let’s Encrypt certificate automatically until the issue is resolved. Check our [troubleshooting guide] for more information on how to fix the problem, and then renew the certificate.

That’s a Google Search issue, nothing that we can do to fix it.

It happens sometimes, safe to ignore.

The last issue seems to be resolved.
