I was trying to connect up using my personal hotspot. I turned it on, and it seemed to start up normally. I turned to my computer, which saw the connection, but couldn't successfully make a connection. When I looked back at my iPhone, the option was completely gone. I then went to the general -> network panel, and I see the personal hotspot, but the option just has the "wait spinner" going with no buttons. This persists even after powering down and restarting the phone.
What do I need to do to get this back up and running.
A possible side effect is that I don't seem to be able to connect to my VPN, but that might be an unrelated issue with my VPN provider. Not sure....
