Connectivity Framework Error when connecting from PCo to MII

Hi Experts,

i'm trying to get a connection from PCo to MII.

If I check the box for the untrusted certificate, the connection can be established and i can choose transaction from the MII to send a notification.

Problem is, I can't use the tags from the plant information catalog in SSCE.

I guess this is because of this issue here...

The error message is the following:

The error in SSCE, when using th etags from PIC:

The browser console says something about the websocket subscriber, so I guess the I need to establish a secure connection from PCo to MII to solve this problem.

Any help would be appreciated.

Thanks and best regards.
