    Definitely weird. WiFi connections are poor, but VPN connection over the same WiFi link is good.

    That makes me think perhaps DNS like others have said, or it could be something with your local routing table trying to reach something that’s not reachable. I would probably check the routing table first for anything weird. Like, you might have a static route applied from DHCP, but it’s ignored by your phone OS.

    Since you can reproduce it in the browser I would probably look next at browser dev tools (F12). Go to the network tab. Then reproduce the problem. Once the task properly finishes, hit pause and sort by duration. You can also right click the headers and add a Timings>Latency column. See if there’s anything interesting.

    Like, are the slow steps hitting a new domain name? Is there a slow POST among faster GETs? Is a step repeating after a timeout?

    If nothing’s obvious there I would be tempted to repeat but lower level with wireshark to get the whole network picture. Get a good capture of the problem with a general sense of the timing of the problem pauses (in seconds from the start of capture). Find them in the cap and see what’s what. Compare good vs bad if no clear trends present themselves.

    Ok, so it’s probably using NetworkManager. I would try disabling it in /etc/NetworkManager/NetworkManager.conf by adding a block like:

    [ipv6]
addr-gen-mode=stable-privacy
method=disabled

    Then sudo systemctl restart NetworkManager. Can’t say for sure if this will work. I dislike using NetworkManager on my servers so I can’t test if this works. But hopefully the before/after of ip addr is different.

    Although it looks like your ip addr output posted an hour or so ago doesn’t show any ipv6 addressing. Maybe the problem is solved now.

    Different programs have different defaults.

    But in your situation which would be more helpful - prevent this one docker command from using ipv6 (likely more difficult), or preventing all commands from using your broken ipv6 config (likely easier)?

    I have no idea about the first. Maybe some people know this detail. But I’m sure that with a distro and version that you’re running, there are lots of people who could help with the second. Raspberry Pi 3B+ is the hardware. What software are you using?

    Docker is a distraction in your problem description.

    It’s like if you asked why the top gear in your car isn’t working and gave the model of car and engine type and gearbox. But it’s really that you’re stuck in slow traffic. Focus on the road name and destination to find a faster route.

    For your problem, search for how to disable ipv6 for the Linux distribution and version that you have installed. You will find lots of guidance. Or share those details here for someone to help.

    Or, better might be to see if there is a way to get ipv6 tunneling working on your connection. It may be possible even if the ISP is unhelpful.

    openSUSE Tumbleweed is the rolling release, where you may have dependency decisions to make during regular updates. Updates must be done in the terminal.

    The more beginner friendly version is openSUSE Leap. That has a longer release cycle, and you use the Discover interface (or yeast, or zypper in the terminal) to update.

    Either is pretty friendly. Both have recent KDE.
