Cox Hotspot

I have been able to successfully connect to a mobile hotspot for awhile now, but, over the past few days, I have not been able to connect to it. 

The network, "Cox WiFi," still appears on the list of available networks. It also has three bars, indicating that there is a strong signal. Whenever I click on it to connect, it does not connect. The "waiting wheel" continues to spin.

I have tried "forgetting the network," connecting multiple devices to the network, and restarting all devices before trying to connect to the network again, but I have not been successful. 

I would greatly appreciate any troubleshooting tips, or for the hotspot to be fixed. Thank you!
