Cannot get interface to work with ISP

My RHEL 7.8 machine functions as an offline system, no internet connectivity. I configured an IPv4 connection to use DHCP and try to connect to my ISP so I can pull updates. I create the connection and plug it in, I then click on the connection and when the interface tries to set an IP, I get an error from the Networking Interface "Connection Updates failed". Updates is the name of the connection I have created. After this error, I can ping googles DNS servers but, I can not resolve DNS or access any websites. Could I have maybe created the connection wrong? My Linux experience is minimal. Thank you everyone for your time in advance.
