My CCGX is currently without internet. To log data for the VRM portal, I have chosen to upload the backlog buffer manually by removing the storage device from the CCGX, a microSD card, and inserting it into my laptop and uploading the data file on it onto the VRM portal with the “Upload CCGX File” option. I did this once successfully but thereafter, I have been receiving the connection error message below on my CCGX. What does this error message mean?
