HI
I'm setting up an ArcGIS Monitor 2023 on an ArcGIS Enterprise installation in HA.
all components have been successfully registered except Portal for ArcGIS.
when I register, the Monitor only warns me of a problem without specifying anything else.
I also opened a Browser with the user running the ArcGIS Monitor service to check if it successfully reached the Portal correctly.
I tried to register both through WebAdaptor and through port 7443 but without success.
i managed to catch the error via the Browser with specified token error.
below is a screen

Thank you
Virgilio
