Blank thumbnail on Facebook share

Hi there,

I checked the url of the image captured by the og:image meta tag in the HTML source of your webpage https://www.newjobsinassam.com/latest-jobs/assam-forest-department-recruitment-2020/ which redirects to “page not found”. The url of image captured by the og:image meta tag will be shown in the content of the webpage shared. You would like to check if the images captured by these tags in the HTML source of your webpages are appropriate.

This is very complecative for me, I am a beginner

If you drop email at support[at]heateor[dot]com, would be able to help.
