I have a domain DNS managed by Cloudflare https://scnv.io for the last few days, users have reported that they are not able to access the URL in Saudi Arabia.
I just had a call with the customer in Saudi Arabia and we tried 3-4 ISPs and with a few of them the site loads once and then does not load next. So on refreshing the page 5 times, the website is opened once.
Currently, the DNS is not proxied. When I proxied the domain, it works fine but without it, it does not work.
I also tried other DNS checkers (with non-proxied)
