This is a summary, based on reports elsewhere on the site...
The servers are routinely being worked on, but they are also still working on making things right after the update.
The server people are working on getting all boxes up on the service, in particular the Avovs. Boxes are missing channels, but VoD is available.
As far as the STB Emulator, and the official customized versions, they also appear now to be connecting, but not with full channels. [There are reports that the customized version may not be working, but they should also work after an "IPTV Reset".]
For Kodi, PVR Stalker and PVR Stalker NFPS should be working, however the direct load of the XMLTV file from epg.ninja is under maintenance. Select "Prefer XMLTV" to allow a load of the guide from the 'provider'. IPTV Stalker no longer works with reset or new MACs.
