have been using this plugin for quite a while and getting a lot of value out of it. i offer thanks to the authors for their efforts and the community who help provide support.
recently, i looked and found that none of my charts were working. the grafana dashboard pages are empty and anywhere there was perviously a graph is blank with a red triangle at the top. if i click the triangle, it exposes some information about the error. it seems i'm getting a message of "InfluxDB Error: Bad Request". It also says "Authentication to data source failed". same errors and messages appear for all the graphs in all of my dashboards.
any ideas how i might go about correcting this problem?
