    Just to let you know. Had a look. Seems to be ipv6 related. Disabled ipv6 and all connected. Something went wrong on DNS lookup for a PTR.

    not had change to dig into further, but maybe same for all.

    I disabled ipv6 with this command if you want to try

    sudo sysctl -w net.ipv6.conf.all.disable_ipv6=1

    Unfortunately it is more than that I think. I disabled ipv6 without any change.
    Look at this thread: https://forum.flightradar24.com/thre...385#post106385

    Same here in Canada.

    Last night I made a fresh install (Raspbian Stretch + dump1090-mutability v1.15~dev + fr24feed). The fr24feed-status showed feed failure.
    [FAIL] FR24 Link: unknown ... failed!

    Thanks to tech007 for his post #24 and post #893, I fixed it by following command given by him.

    Code:
    sudo sysctl -w net.ipv6.conf.all.disable_ipv6=1

    FYI, I too have run into connection issues, which might be related to IPv6, which is strange as I have a full IPv6-enabled network at home, and the connection would work the same via IPv4 or IPv6. Go figure.

    Nonetheless, it was clear that the issue was related to IPv6 when I decided to create a simple hack which would force IPv4-only connections, of a very different kind than blocking completely IPv6 (which I DON'T want to do!) and neither changing the configuration of the getaddrinfo config file /etc/gai.conf.

    The hack consists of fixing the IP address of the initial connection to feed.flightradar24.com and its CloudFlare counterpart to a fixed IPv4 address, which will take precedence over a DNS-resolved IP address.

    Here is what I added in /etc/hosts:

    # hack to fix the IPv6 issue with feed.flightradar24.com.cdn.cloudflare.net (104.20.0.101) - solved on 2018-08-25

    104.20.0.101 feed.flightradar24.com
    104.20.0.101 feed.flightradar24.com.cdn.cloudflare.net


    Obviously I now have a fixed IP address and not a dynamic one out of a pool, and if FR24 someday decides to change the IP address of the feed, I will need to modify it by hand.

    By doing this I was able to make my newly refreshed RasPi 3, which used to run Jessie and now runs Stretch, work again after the dist-upgrade which crippled fr24feed.

    Bye, Luca
