This is your own network error. Check the firewalls for the UDP ping port which defaults to 25565 for Minecraft. ICMP pings are an entirely different protocol.

[PerchunPak]

Same command on my windows computer

[kevinkjt2000]

Again check your firewalls. Clearly mcstatus is working but is being blocked on TCP/UDP from the Linux machine you were using. I’m quite certain that termux makes no difference. (Unless there’s an additional firewall that only applies in termux)

[PerchunPak]

Yep, you right.

~ $ nc -z -v hypixel.net 25565
nc: connect to hypixel.net (104.16.78.21) port 25565 (tcp) failed: Connection timed out
nc: connect to hypixel.net (104.17.71.15) port 25565 (tcp) failed: Connection timed out
nc: connect to hypixel.net (2606:4700::6810:4e15) port 25565 (tcp) failed: Network is unreachable
nc: connect to hypixel.net (2606:4700::6811:470f) port 25565 (tcp) failed: Network is unreachable

One question is left, how disable firewall in my MIUI? Seems like this question will left without answer.

[kevinkjt2000]

Yes that question is beyond this issue tracker. The best we can do is point out that the network port is being blocked.
