DNS server 220.127.116.11 is no longer working on my network, only 18.104.22.168 is listed as “accessible”. Also, when I try to access https://22.214.171.124/, an “ERR_CONNECTION_REFUSED” error occurs. Do you know what might be happening?
And here’s the tracert to both servers (126.96.36.199 and 188.8.131.52). Would it be a route problem with my ISP?
It would seem as if your ISP hijacked that address and does not route it to Cloudflare. You’ll need to contact your ISP in this regard.
