Problem with the manager.streetartnetwork.com

Hi, I can’t work in my manager.streetartnetwork.com. My browser mozilla firefox let me know the following in german:

manager.streetartnetwork.com verwendet ein ungültiges Sicherheitszertifikat. Das Zertifikat ist am Dienstag, 3. Oktober 2017, 01:59 abgelaufen”
Is there anybody who can tell me what’s going on??
Thanks an cheers

Hi Dieter, apologies for the slow reply.

We retired the domain name streetartnetwork.com some time ago, and are now only using streetartcities.com, so you can sign into the manager using this address:

:earth_americas: manager.streetartcities.com

I hope that works, apologies for the inconvenience!
