For me it’s working from both non-www and www versions. If it doesn’t work from the non-www version, please clear your browser cache, flush your DNS cache or, if it still doesn’t work, configure a faster DNS resolver, like 1.1.1.1, OpenDNS or Google Public DNS on your device.
The hosting platform itself does not enforce any kind of automatic HTTPS redirects. We provide the ability to use SSL on your website, but it’s up to you to decide how your website uses it.
Clearly, there is some kind of HTTPS redirection code on your website which redirects people visiting www.protechtion.in to the HTTPS version of your site. Maybe you can configure this redirection to also work on protechtion.in? I don’t know what software you are using, so I don’t know how you need to configure this. Maybe the documentation of the software you’re using has more information about this?
