Answer 1

In some cases It's only because of poor or interrupted internet connections

One solution might be changing your internet form Wi-Fi to Ethernet.

---

If you are using ESET antivirus, go in "Advanced Settings" and disable "HTTP-scanner" under "web access protection"

---

If you're using Virtualbox, Then you might need to downgrade to resolve the issue

---

If you are using IPv6, try disabling it.

sudo sh -c "echo 'precedence ::ffff:0:0/96 100' >> /etc/gai.conf"

Answer 2

If you are using ESET antivirus, go in "Advanced Settings" and disable "HTTP-scanner" under "web access protection"

If you are using IPv6, try disabling it. If that solves your issues, get in touch with your ISP or server host, the problem is not at the Packagist level but in the routing rules between you and Packagist (i.e. the internet at large). The best way to get these fixed is raise awareness to the network engineers that have the power to fix it.

To disable IPv6 on Linux, try using this command which appends a rule preferring IPv4 over IPv6 to your config:

sudo sh -c "echo 'precedence ::ffff:0:0/96 100' >> /etc/gai.conf"
