Some IPs can not open my website

I don't think this is an Let's Encrypt issue. You probably should contact your hosting provider and figure out if they have any comments...

Let's Encrypt isn't doing anything to prevent users in Iran from visiting the sites it certifies. (In fact, Let's Encrypt has fewer Iran-related restrictions than most certificate authorities.)

It could be that some hosting providers are blocking connections from Iran (as a way of trying to enforce U.S. government sanctions) or that Iranian ISPs are blocking connections to some sites (as a way of trying to enforce Iranian government censorship rules). We can try to figure out which of these is more likely to be the case if you can give some examples of specific sites and specific error messages that users in Iran get in their browsers, but we may not be able to do anything to fix the situation ourselves, unfortunately.

There's a slight chance that Let's Encrypt's OCSP endpoint is getting blocked for some reason, in which case the issue would be more widespread but would still depend on which browser people are using and how it's configured. That should also be visible in the browser error message, in that case.
