I received a free ArcGIS Pro license due to my participation in the GIS Day activities organized by my organization last year. I've managed to setup everything fine in my machine to use the ArcGIS Pro license and every was going smoothly until today.
Our office is in the midst of migrating our domain and mine was done today where ArcGIS Pro is already installed in my new domain. But when I try to login, it gives out this error:

I have already uncheck the option to take the license offline and had done all the things to ensure that this problem does not occur. But it seems like it happens anyway. And I tried to get tech support but I can't request a case. My colleague mentioned it may due to the limitation of this license. Moreover, I was informed that the only way to fix this is to have the tech support revoke my license at their end and 'reassign' it back to me.
Anyone have any idea how I could fix this?
Thanks,
