Obtainium 1.1.55

I have had trouble with this on various sites in the past, though it always cleared up if I waited. That's not the case now, and I'm wondering if it's related to this issue.

Without any changes to a profile for this site, and with the appropriate .apk downloadable with a browser, I get repeated "Not Found" errors in Obtainium. I checked the logs, and you can see nothing past May 20th (it's now the 24th). You can see the images below.

The setup is to access via HTTP: https://download.linphone.org/releases/android
Custom APK link filter by regular expression: linphone-android-[0-9.]*\.apk
Version string extraction RegEx: linphone-android-([0-9.]*)\.apk
Match group to use for version string extraction: $1
Otherwise, all switches are off save "Attempt to filer APKs by CPU architecture if possible"
