Kodi 18 git, TVDB 3.0.1 returns "ERROR: Run: Unable to parse web site"

New Kodi user here.. Debian Linux, new install of Kodi 18 git from a few days ago, TVDB 3.0.1.. I added a video source with a couple test shows in it, set it to contains "TV Shows", then tried to update the library. I see a few temp/scrapers/metadata.tvdb.com/search-*-en.json files populated with show descriptions in them, but nothing wound up in the library. Googling that error I came across disabling ipv6 in userdata/advancedsettings.xml, which I tried, and which had no affect. I see in the logs:

Full log is at: http://paste.debian.net/1001170/

My dir structure, from what I read, should be ok. kodi.library/TV is the video source I added, which contains only:

kodi.library/TV
kodi.library/TV/Stranger_Things
kodi.library/TV/Stranger_Things/season_1
kodi.library/TV/Stranger_Things/season_1/stranger.things_s01e01.mkv
kodi.library/TV/Stranger_Things/stranger.things_s02e01.mkv
kodi.library/TV/Humans
kodi.library/TV/Humans/humans_s01e01.mkv

Any help is greatly appreciated!
