404 not found

When using your phone app and can't communicate with the car because of a "404 not found" error it may be your router's DNS service.
I was getting this error and tried restarts and reinstall etc. Nothing worked.
I went into the router's set up page and changed the DNS service - fixed the issue immediately.

Good note. It might have been due to your ISP's DNS caching, so switching to another provider can help. Or waiting a while for it to expire and pull fresh info.

You may still encounter the same issue with your new service the next time Tesla makes a similar change, because most DNS services cache queries for at least some amount of time.

I was seeing that error yesterday on my iPad but not my iPhone. Force quitting the app on my iPad and relaunching fixed it for me.
