Error when adding Plex backend

[Rhytox]

Hi

I want to use watchstate to sync the watch status from Emby to Plex.
I succesfully added Emby as a backend but a problem occurs when adding plex as backend.
At the final step, when clicking "Add backend" I get this error:
Failed to Add backend. (400: Failed to connect to backend. TLS connect error: error:0A00010B:SSL routines::wrong version number for "https://172-26-0-....

So it loads the users correctly, I can select the user and mark this backend as import but the final button gives the error.
