IP Range/AS Banded?

All our IP range: 2803:1920::/32 is blocked, we can’t access to discord too, and all website hosted by cloudflare. Eg:
curl -o - -I -v ‘Speedtest by Ookla - The Global Broadband Speed Test

  • Trying…
  • Connected to www.speedtest.net ( port 443 (#0)
  • ALPN: offers h2,http/1.1
  • TLSv1.3 (OUT), TLS handshake, Client hello (1):
  • CAfile: /etc/ssl/certs/ca-certificates.crt
  • CApath: /etc/ssl/certs
  • Recv failure: Connection reset by peer
  • OpenSSL SSL_connect: Connection reset by peer in connection to www.speedtest.net:443
  • Closing connection 0
    curl: (35) Recv failure: Connection reset by peer

How solve this?

Does your IP addresses get banned by ISP/Telco? Please kindly understand that Cloudflare doesn’t have control over the ban/block policy of ISP/Telco. You can contact your ISP/Telco directly regarding this.

I’m the ISP/Autonomous system, I remain investigating…

That looks like it didn’t even get as far as Cloudflare.

How does an MTR over Port 443 look?
