General info
Kernel: 6.17.9-2-cachyos, but problem persists for around a month
Location: Russian Federation, Crimea
Problem
Both paru and yay hang indefinitely when trying to install packages from AUR. Regular pacman works fine, and system updates through paru -Syu work, but package installation commands hang:
paru -S <package>- hangsyay -S <package>- hangsparuhangs after updates at “Looking for devel upgrades” stage
The issue persists even when using VPN or proxychains with my own proxy server.

5. Proxy test

[proxy works for Google]
But for https://aur.archlinux.org:

6. VPS diagnostic (where proxy server is hosted)
# curl works with hostname
bio@vps:~$ curl -v --max-time 10 https://aur.archlinux.org
[Returns normal HTML content]
# Direct IP connection hangs
bio@vps:~$ telnet 95.216.144.15 443
[hangs indefinitely]
# Traceroute
bio@vps:~$ traceroute 95.216.144.15
[reaches 95.216.129.164 at hop 14, then * * * afterwards]

- ✗ Various paru/yay configuration changes
Additional info
A friend in the same city using the same kernel is experiencing similar issues, but even worse - pacman itself doesn’t work for him, not just AUR helpers.

How can I fix this?
