Unable to load summary from remote flathub [OT]

Hello, i face this error while trying to install any flatpak from flathub connected to wifi (ADSL) network but there’s no issue when i switch to mobile data

flatpak install flathub io.freetubeapp.FreeTube
Looking for matches…
error: Unable to load summary from remote flathub: Error resolving “dl.flathub.org”: Name or service not known

also i feel uncomfortable asking this here, please let me know if it’s OT.

There is very little fedora related that would be considered off topic here and this certainly is not. Please ask any questions you have and support should be available.

This is info about how to enable flathup as a software source. Although an older article it probably still applies. I don’t use flathub so have not set it up on my system.
