upon checking on facebook the site is not recognize and it shows 404 when fetch to facebook here is screenshot
Is this related to Discourse? If so, what are you trying to do?
Yep, looks more like a transient connectivity problem between Facebook and your server.
iframely.com/debug finds all relevant Open Graph data without problems.
DId you try the Fetch new scrape infomation button?
is there additional code needed to add in order to discourse add the images on the OG:image ?
That’s a long story
There is a 500 error when crawler hit your Discourse. Didn’t you edit anything or place any proxy in front of your Discourse
Finally Fixed it
added this line of code with the .conf file
listen 80; listen [::]:80;
and as I fetch it worked
yes I did used docker
