Subzero Doesn't show in Agents

[Robbinvw]

Hello,

I had Subzero (2.6.5.3268) running on Synology DSM 6.2.4 perfectly!
After I updated Synology to DSM 7.0.1 and updated to Plex 1.25.5.5492 with the same Subzero version. Subzero stopped working:
It doesn't show anymore in the agents list so I can't acces it anymore.

Thank you in advance for your help.
