It's not about the Babiato doman extension it's your ISP who may be blocking connection to the forum website. Try a different ISP, mobile data or use VPN.I'm really disappointed. Can you update the domain to .net or .com or .org or whatever? Many countries blocking sites with .co extension. @Tomz
use opera gxVPN working fine but not working with mobile data or any other methods. Please fix this from cloudflare rules. @Tomz
