I have a dashboard which seems to have issues posting to Raintank.io. When I press publish is I just get a endless spinning and no url to look at for the dashboard. I also increased the timeout to 9999 as 4 wasnt working without throwing an Unexpected error . Is there a log or limit when posting to raintank.io? Along with that is there an easy way to host a web facing version of the graphs without exposing my graphana instance to the internet?
