This looks like a virtual machine, could please share it's IP or at least the ASN used, this looks like rate limiting gone wrong.

this ip : 193.163.200.248
There is no problem in the browser
thanks for this

is that a browser from the same machine?
what if you use something else (e.g. currl)?
the wget output indicates it's using ipv6 but you've given an ipv4 address

yes

what if you use something else (e.g. currl)?

curl : curl -O -L "https://go.dev/dl/go1.21.6.linux-amd64.tar.gz"

I would appreciate it if you could provide more explanation about the last solution. I cannot use wget under any circumstances and I still receive the same error.

Does wget -4 https://golang.org/dl/go1.21.6.linux-amd64.tar.gz also fails ?
It would be nice to know the IPv6 address of the machine too.

I used this method: this ok.
wget --inet4-only https://golang.org/dl/go1.21.6.linux-amd64.tar.gz

But I am encountering this error again during extraction:
:~# tar -xvf go1.21.6.linux-amd64.tar.gz

gzip: stdin: not in gzip format
tar: Child returned status 1
tar: Error is not recoverable: exiting now

It says:

Saving to: ‘go1.21.6.linux-amd64.tar.gz.3’

wget saw that Saving to: ‘go1.21.6.linux-amd64.tar.gz already existed and did not overwrote it, instead it saved to go1.21.6.linux-amd64.tar.gz.3.
So tar -xvf go1.21.6.linux-amd64.tar.gz still try to open the original failing download.

Can you please show ip addr for the IPv6 address as IPv4 looks to be working ?

Thank you very much, the extraction was successful. I deleted the previous files and reinstalled it. And as you said @seankhliao
@Jorropo , the problem was with IPv6 and IPv4.
