Faulty Module?

Hi, last week I bought a Nissan Leaf 2015 and it comes with ovms, parked at my garage and connected to wifi/GSM it works, but after a short trip the module resets itself and I need to configure everything again, what can be wrong? I've tried disabling GSM, without CAN write with same result, I've installed a new SD Card and tried to backup my configurations but I cannot create files under /sd/backups, or create more logs apart from this:

Any advice? Thank you.

Faulty Module?

If you keep losing your configuration, try doing a factory reset, so the config partition gets reformatted.

If you cannot write to a new SD card, that SD card may be formatted improperly or be defective.

You may be able to get a hint from the log output, which can be monitored live from the web UI (shell). Set the log level to debug to see more details.


I've deactivated TLS and it

I've deactivated TLS and it has been working for the last two days, but I'm going to try the factory reset to fix the issue with backups (log is being saved to sd without problem), thank you dexter:


After factory reset everything looks to work fine
