So it’s a common error that the social media post is not publishing.
For Image Rejected error check that your post image is within the size limit and the size parameters recommended for the social network, you’re posting to. Also, check the picture’s file format is JPEG or PNG and that the image URL is still live.
For Authorization failed error, check your authorization in HubSpot.
Third-party network issue – Check your image is valid and you have the authorization as mentioned above. After it clones your social media post you can publish it.
If the same error occurs again then contact the HubSpot Support
Facebook Limit- Facebook has a limitation in HubSpot so it may affect your posting so wait till the limit adjust over 24 hours.
Hope this helps
