3G/4G mode on GL-MT300N-V2 not working

After trying to connect through the normal config I went to advanced to look at the logs. I keep getting “Could not determine remote IP address: defaulting to 10.64.64.64” when trying to connect through 3g/4g. Is there a simple fix for this? I bought this for its compatibility with 3G/4G.

I’m using a ZTE Mobley (VM6200) connecting to a GL-MT300N-V2.

Are you connecting to Mobley via WiFi or USB?

I’m connecting through USB.
