Some clients have troubles while connecting my site.
22.214.171.124 and 126.96.36.199 as sample receive network timeout by OS, not any pages of Cloudflare. User in 188.8.131.52 network ask your friends in the same provider, and they can’t connect too…
I asked clients to diagnose, but they not network specialists. Ping my site olegon.ru resolved it to 184.108.40.206 and 220.127.116.11, but can’t connect it in all browsers and by mobile device.
telnet olegon.ru 443 and telnet 18.104.22.168 443 hangs by network timeout too, but works very well on some other sites from the same host.
most of other clients connects without any problem and run telnet command above with succesful connection.
I whitelisted 22.214.171.124, but without success.
Is any hidden blacklist of IP? Is all normal blacklisted receive block page without simple blocking (such as drop packet)? How to unban this networks?
