Failed to check extra-data

[Mailaender]

src.manifest: Failed to check extra-data 7kaa/7kaa-music-2.15.zip with URLChecker: Error downloading upstream source: Connection timeout to host https://www.7kfans.com/downloads/7kaa-music-2.15.zip

in flathub/com.sevenkfans.sevenkaa#1 where manually the download works just fine.

Maybe it is related to this issue, on which the problem seems to be choosing IPv6 and no IPv4

• More debug when HTTP checker fails #331

Testing locally works fine, only IPv4 connectivity
