I get "ERR_SSL_PROTOCOL_ERROR" on my website

I deployed my website yesterday and it was running smoothly. When I woke up in the morning, I saw that I got an “ERR_SSL_PROTOCOL_ERROR” error. Then I tried with my phone and the same error again. After that, again I tried with my phone but this time I used my GSM operator internet, not the Wifi, and my site opened I didn’t get the “ERR_SSL_PROTOCOL_ERROR” error.

Then I tried accessing my website with a VPN on my computer and I was able to open it again. When I sent my website to my friends, they also could not log in to the site without a VPN, just like me. What is the reason for this and how can I fix it?
