Wordpress image not loading in telegram Why?

Question

WordPress

A very strange situation...
1) There is an article on WordPress
2) We throw it off in Telegram
3) Depending on the utm tag, the preview disappears for some reason

Let's specify the number 6 = the preview is loaded


If we indicate the number 1 = the preview is not loaded


If we indicate the number 7 = the preview does not load, but something changes


The numbers do not matter, you can try different ones and in the end it always somehow changes.

What could be the problem?

Here is the link, if you need https://newsgulding.ru/sadlfjhg.html?link=6 - here the picture is loaded, but if you replace 6 with 1 at the end, it is no longer loaded.

Answer 1

Telegram caches preview links. Therefore, it is useless to change something on the site when he has already remembered the wrong thing.
Solution: we find the WebpageBot bot, enter a link to it - and it updates the preview on the Telegram servers. Just did it with the given link and it worked.
