Unable to re-register endpoint to EMS

Hi,

I've come across a bit of an issue as I've been rolling out Forticlient to our internal network.

I installed it on a handful of servers to test before rolling out to the entire network and there were no real issues. However I have excluded a couple of those endpoints from management from within the EMS console (as we were trying to decrease resource utilization on them) and now am completely unable to re-register these devices, there is no option to register device in the drop-down actions menu. The only options are "exclude from management", "clear events" and "mark as uninstalled"

I have played around with this but nothing forces the connection to re-establish, it's stating not managed by the EMS/Gateway List and the profile. I have tried re-profiling the endpoint but again this hasn't been helpful.

On one of the endpoints I even selected mark as uninstalled and re-installed forticlient on the endpoint in the hopes that the connection would establish but no such luck! In fact the endpoint doesn't show in EMS at all now.

On a side note, I have added other systems successfully to EMS and they are connecting and communicating with no issues, it's just the 2 systems that I excluded that won't talk at all.

Any help would be much appreciated.

Thanks
