When I share my website in other places, the web preview does not appear.
If I share it in telegram, only the link appears.
When I try to share on Facebook, the same thing happens to me as to this other person: https://support.cloudflare.com/hc/en-us/articles/217720788-Why-doesn-t-my-site-display-correctly-when-sharing-to-Facebook-
if I disable cloudflare, it works perfectly and I can get the preview.
I do not have any firewall rules configured, everything is according to default, I just enabled https.
I hope someone can help me, thanks!
