Recently I suddenly can't download the images and pool galleries with my IDM anymore, every time I tried to resume downloading it gives error message "An error occured whle creating security connection to yande.re".
But I can open the original images and download the pools with my browser just fine.
Anyone can help me on this?

don't use any download manager please

The use of download manager is fine up to the connection limit. While you use it, you may not be able to surf the site. Any how, I have no such problem using the same software. Perhaps you are using a very old OS or your IDM is using an old TLS connection.
