Update won’t download, and feature images not working with social share

The post I need help with is https://independentamericancommunities.com/2019/02/15/debunking-hoa-ads-press-releases/ Try the share buttons at the bottom of the post for Facebook and Linked In — then check your accounts to see what I mean. FB displays a 403: forbidden error where the image should appear Linked in displays text but no image Could this be related to the new update 5.02? I tried to download it, but the download isn’t working.
