Devices can't connect to DTEK50 Hotspot

All my devices stopped connecting to the blackberry Dtek50 hotspot from two days ago. It gives an error saying IP could not be resolved or No Internet access on my devices. I have tried an iPhone X, Samsung S7 and Dell Laptop. I am allowed to use the hotspot, and have been using it since I got the phone around a year back. I can connect to the hotspot of my colleagues blackberry, so it is not a problem from the service provider nor is it blocked by the company.
