I’m trying to access a site which requires me to solve a captcha. upon solving the captcha, i receive 520 error page, indicating that something is wrong with the server i’m connecting to, while showing that Cloudflare’s servers are working fine. However, when I connect to a neighbor country’s VPN, I’m able to access the site without having to go through the captcha page, and the site is working fine.
I’m sure that this is not the web server’s issue right now as a simple VPN connection to a neighbor country solved the “520 error that indicates something wrong with the server”. May i know if there’s any other possible causes that this can happen?
