Hi. I’ve encountered this problem since early April, but started noticing it more clearly as the calendar moved towards mid April.
For context: I have 2 computers, one is my older, Intel/Nvidia gaming PC turned general-use web & chat computer and the other is my all-new all-AMD gaming PC.
The older PC is an Intel Core i7 8700 with a Gigabyte Geforce RTX 2070 and 16 GiB RAM on a Gigabyte B360M D3H-CF mainboard.
The new PC is an AMD Ryzen 7 9800X3D with a Gigabyte Radeon RX 9070 XT and 32 GiB of RAM on a Gigabyte B850M Gaming X mainboard.
Both of my computers are connected to the same LAN Switch, which is connected to a MoCa device (converts Ethernet signals to Coaxial signals, the old cable television technology), and from there to the household router, a FortiGate corporate router where my MoCa is designated as DMZ (no security measures are applied to the connection).
When this problem started, I had Tumbleweed installed as the OS in BOTH computers.
A few days into the problem, I decided to follow a hunch I had and installed Linux Mint on the older PC.
I can confirm that this problem does not exist on Mint at all, as it downloads all software packages from any and all sources, especially Flatpak, quickly and perfectly smooth. So this problem is specific to OpenSUSE Tumbleweed (Leap not tested).
The problem is twofold, but I believe there is just one thing causing it that I’m unaware of due to my lack of technical know-how (I am a relative normie).
When I try to download or update packages from Flathub, be it via Discover or thru the terminal, I am informed that a hostname could not be resolved for http://ciscobinary.openh264.org/libopenh264-2.2.0-linux64.6.so.bz2.
Running Flatpak in the terminal lets me proceed with installing software packages regardless of this malfunction, but trying the same with Discover has me greeted with a very long delay and then an error message mentioning the above most of the time.
Downloading updates for Flatpaks and their dependencies via Discover will, most of the time, result in the same. It is rare that Discover succeeds in downloading updates for Flatpak programs.
For extra context: it’s not just one particular package. I’ve installed Discord, O(pen)B(roadcaster)S(oftware) Studio, LibreWolf and more, all of which require that particular OpenH264 package.
Aside from this failure to resolve hostnames for that package AND MY BANK’S WEBSITE, downloading packages from Flatpak is also very very slow - just a few hundred Kbps. Installing Flatpaks takes almost an hour at this rate.
On top of that, my Mint OBS cannot receive any video stream from my Tumbleweed OBS with both the Teleport plugin and the NDI (DistroAV) plugin (despite the fact that Mint OBS can [detect] the existence of the Teleport stream from the TW OBS).
Again: Mint downloads fast and smooth with no such connection issues. that OpenH264 dependency package is downloaded and installed without incident, installing Flatpaks takes mere seconds and my bank’s website is fully loaded before I can even blink.
Tumbleweed can still connect to the internet and load up websites, tho. YouTube, FlatHub, whatever - MOST websites will load just fine. Steam and Lutris can download games as well, without any slowness. it’s just that there are a few websites that the TW computer cannot resolve the hostname of, for some reason.
I’ve tried fresh-reinstalling Tumbleweed from a newer ISO, to no avail. I’ve sadly neglected to keep older installer ISOs from the month of March or earlier.
I am at a loss for solutions and workarounds at this point. Any help will be greatly appreciated. Thanks in advance.
