@julien-f Agreed... I will add (just for future reference) that I did confirm that I was on the very latest versions of xo-server at the time... in fact, I made sure to apply all updates and reboot the Xen server before submitting the ticket.
Nothing seemed to work... even multiple reboots, etc. Once @Danp made mention of the Nodejs version and I updated from v18.18.2 to v18.19.1 everything immediately started working. I made no other changes after applying the Nodejs update.
So while that may not have been the cause, it somehow fixed whatever was ailing me. I have no explanation either, other than the fact that making that change is what took me from the feature not working to the feature working. 🤷
