Connection to dl.flathub.org fails. As the result, Flatpak neither updates, nor new software installations work. Interestingly enough, it resolves successfully and responds to pings. It’s just HTTP(S) traffic that gets blocked.
The problem started around a week ago, maybe a bit more.
Here’s how “flatpak update -vv” fails:
F: No installations directory in /etc/flatpak/installations.d. Skipping
F: Opening system flatpak installation at path /var/lib/flatpak
F: Opening user flatpak installation at path /home/jiube/.local/share/flatpak

And here’s what the output of “mtr -T -P 443 dl.flathub.org” after some time running looks like:

I should however point out that dl.flathub.org responds to pings for me and sending ICMP packets to it via mtr instead of TCP port 443 packets looks like this, actually:

It is fairly normal that not all of the intermediate nodes respond to packets, so TCP not getting a response on step 6 is not necessarily invalid as long as the connection gets passed along. But it seems that it doesn’t connect beyond this point.
So, it’s clear to me that connection stops either at this 80.249.212.184 host (which appears to be somewhere in Amsterdam) or at the final destination of 151.101.1.91 (which is the Fastly node my connection ends up routed through), and it only blocks HTTP(S) requests with ICMP requests passing through just fine.
As you can see from the output I shared above, it’s neither my local setup, nor my local ISP blocking the connection.
Flathub lacks any official repo mirrors (and I failed to find any unofficial mirrors too for that matter) which makes it tricky for me to resolve this problem by just using some other repo. Unless you have some repos in mind to suggest I used. That lack of mirrors is quite a shortsighted approach, IMHO, but I guess there’s nothing I can do about that. In any case, I’m frankly out of options.
So, I have a question to the Flathub team. What solution do you propose that will fix this? Is it something you could fix? Do you need any additional information from me to do that? Or should I contact Fastly to unblock me or something? What’s the path forward from here?
