Unable to connect LTE

Dear Nordic team, 

I am unable to connect to LTE network through AT_client although I have successfully connected to the LTE network within the same area and it was working fine. I am not able to connect to the LTE currently and I have no idea why. Can you help to resolve this issue? I have attached my log and picture for reference
