EC2 Instance Temporary failure in name resolution/Empty resolv.conf file

I had a working ec2 instance, but have not logged into it for some time. I wanted to re-visit an old project and when I logged in via ssh I noticed that the storage space had filled up. I am using an influxdb database together with grafana and telegraf, and when attempting to clear up some storage space I started running into this "unable to resolve host ip-<iphere>: Temporary failure in name resolution" when trying to execute some commands. Upon further inspection after not being able to "ping google.com" (" Temporary failure in name resolution" error again) I saw that the /etc/resolv.conf file was completely empty, and it seems that the dhclient did not create this file upon startup of the instance.

I have tried rebooting the instance and stopping and starting the instance, but neither of these worked. Could somebody please give some advice on what to try next?
