(Hello, I opened a topic about my site before, I was given some advice about the solution, but none of them worked, the ssl protocol error still persists, although I tried all kinds of methods, I could not solve it, the strange part of the event is that when I try to create a new site, when I try to create a new site, the same error occurs when I try to create a new site, the site opens only with vpn, it does not open from the normal browser, maybe I tried more than ten browsers, but again I did not get any results. when I want to do http, I get http error (400).)
Getting an ERR_SSL_PROTOCOL_ERROR without a VPN but enabling a VPN fixing it, that doesn’t make any sense to me. The error means that there is some problem establishing the SSL connection, and using a VPN should not resolve that.
Unless some ISPs in your country do something REALLY strange and mangle SSL connections, I cannot explain this behavior.
While also being SSL related, this is a completely different issue.
WordPress ships a file at wp-includes/certificaets/ca-bundle.crt which it uses to verify SSL certificates. However, this file is missing from your website. The way to fix this is to download a fresh copy of WordPress, find the missing file and upload it to your site.
In case more files that this one may be missing, this guide may be helpful:
Thank you for your help
