seems cause of problem is flathub using some kinda proxies..

16376 recvfrom(22, "=|\201\200\0\1\0\5\0\0\0\0\2dl\7flathub\3org\0\0\34\0\1\300\f\0\5\0\1\0\0\10\236\0#\tdualstack\1n\3sni\6global\6fastly\3net\0\300,\0\34\0\1\0\0

16376 close(22)

....

the owner of specific proxies is -
16376 connect(22, {sa_family=AF_INET, sin_port=htons(443), sin_addr=inet_addr("151.101.129.91")}, 16) = 0

.. a fastly - https://ipinfo.io/151.101.129.91#block-summary

the error I am seeing on screen:
root@dino:/home/tesla# flatpak --verbose remote-ls
F: Opening system flatpak installation at path /var/lib/flatpak

error: Unable to load summary from remote flathub: While fetching https://dl.flathub.org/repo/summary.idx: [60] SSL peer certificate or SSH remote key was not OK

how to sort this out?
