Problem blocking my site loading

I’ve been having this problem for two days on a site where I put your plugin and these are the logs
these on the site https://www.aspirapolvereciclonico.it reports dozens of these errors:

[Fri Sep 22 06:37:06.607988 2023] [proxy_fcgi:error] [pid 9535:tid 140188885985024] [client 157.55.39.15:61600] AH01071: Got error ‘PHP message: Connection refusedPHP message: PHP Warning:? getimagesize(https://m.media-amazon.com/images/I/41px-dLb+UL._SL160_.jpg): Failed to open stream: Connection timed out in /var/www/vhosts/aspirapolvereciclonico.it/httpdocs/wp-content/plugins/litespeed-cache/src/media.cls.php on line 699PHP message: PHP Warning:? getimagesize(https://m.media-amazon.com/images/I/31aW-bgaJcL._SL160_.jpg): Failed to open stream: Connection timed out in /var/www/vhosts/aspirapolvereciclonico.it/httpdocs/wp-content/plugins/litespeed-cache/src/media.cls.php on line 699′

what can I do?
The problem is that it doesn’t happen all the time but by browsing the site a little bit the problem comes up and the site stays loading for several minutes and sometimes it gives the error page and sometimes it loads the page, but then it becomes impossible to browse the site
Thanks a lot
