Soft eLicenser Connection problems

I have theoretically a Cubase LE 8 license which came with my Steinberg UR22 interface. But I can’t activate it, because eLicenser permanently throws “cannot connect to the server” errors. I have installed the latest version. I have disabled all firewalls (pc and router), windows defender disabled, still the error. Steinberg support doesn’t reply. Has anyone an idea what else could be the problem?

Seriously, am I the only one with this problem? Is the Steinberg support mail going straight to recycle bin?!

Wireshark shows me this failed request: HTTP 378 HTTP/1.0 503 Service Unavailable (text/html)
So obviously some Steinberg server is not working correctly. Anyone any idea? Does anyone actually WORK at Steinberg?!

Please ensure that eLCC is able to reach ( via HTTP.

If eLCC doesn’t work despite valid network settings, you need to file a Support request and attach a “Support File” (to be created using eLCC).

I had a very similar trouble today.
Make sure you are not trying to use it using a USB3 connector or USB hub.

Use a dedicated USB 1.0, 1.1 or 2.0 port on your computer for the eLC and it should be fine then.

It is a shame that eLC key is not supported on USB3…
