-~~DISQUS~~
+==== Data from unauthenticated device has been received ====
+When transmitting data to the VRM Portal, the device sending the data needs to authenticate itself against VRM. It does this using VRM Authentication tokens.
+If either one of those tokens does not match the ones stored in the VRM back-end, then the transmitted data is rejected by VRM, and an error message is shown on the VRM portal. The error message looks like this:
+{{ :vrm_portal:unauthenticated.png?nolink&600 |}}
+These are the causes:
+  - GX device has been reset to factory defaults, using the venus-data.tgz file as instructed in the manuals. For older GX devices, CCGX, Venus GX, Octo GX, and also older batches of Cerbo GX as well as older batches of MP-II GX and ES-II GX, this will lead to this error message on VRM.
+  - Hacker trying to send false data to VRM.
+  - GX device storage corruption (data partition).
+  - RaspberryPi that has a new sdcard or is re-imaged.
+For "1. GX device factory reset" as well as for "4. RaspberryPi", the solution is to reset the tokens, using the Reset Tokens button in General -> Settings.
+It is thereafter not needed to restart the GX device.
+If that does not resolve it, contact your Victron dealer.
