I am getting an issue that I have seen a few times without a resolution. My set up works fine when connected via wi-fi, but not when I am connected via cellular GX LTE 4G A. I have full signal strength, it used to work fine a few weeks ago. I have checked the time and date, and the troubleshooting for error 152 and 153 in the troubleshooting link others have provided do not apply.
The thing that is interesting is that my SIM card usage shows data usage, but VRM will not connect and show me...
