Issue with loading images in messenger browser

Hi, Daniel,

I checked this site on the Telegram built-in browser and didn't face this issue, all images were displayed well. Could you please specify a messenger with the issue so we could check?

The issue occurs on facebook messenger for android. Hope I understood correctly what you were asking.

Hi, Daniel,

OK, I tested with Facebook Messenger, and I still cannot see the issue. What if you try to delete and send the message with the URL again?

I tried that and images are still shown as white-bordered rectangles. But I also tried opening that link on iPhone facebook messenger. And on iPhone it works for some reason.

Hi, Daniel,

In this case, please try to reinstall the messenger on the device with the issue.

Well, that wasn't a particullary good advice. I deleted messenger cache (usually it works as good as reinstalling app) but it didn't help. So i tried to google this issue thinking it might be more related to wordpress or hosting than nicepage.
And now i found out that that image problem was caused by http and https. For example my logo was "http://test.danielklesc.sk/wp-content/uploads/2022/03/zelene-logo.png" but my site was "https://test.danielklesc.sk/" so messenger app wasn't able to find that image becouse it was searching for image through https protocol but image was "on" http protocol.
So I disconnected my SSL certificate from my web. And now it works.
But of course SSL certificate and https protocol are there for a reason so the solution should be to change every image link from http to https. And that can be done by "Better Search Replace" wordpress plugin.
So I ran search and replace. I searched for "http://test.danielklesc.sk" and replaced all of them with "https://test.danielklesc.sk" so now I hope it will work.
This is where I found this solution: https://wordpress.org/support/topic/images-not-displaying-on-home-page-2/
Please don't make this thread private. It might help someone else who is facing this issue.

Update: I found out that the only thing that needed to be done was to install Really Simple SSL plugin. :D

A bit of necro, but thank you, this finally fixed the issue I been having from the beginning with messenger app...So far the Nicepage team was unable to reproduce or to figure out this issue for me either!
