Does that datasource have segments?

[amoussoubaruch]

Yes my datasource have segments.
The problem is that it worked correctly (Connexion are ok and i make a dashboard) and day after connexion between superset and druid a broke. I have error that i show in my last comment.
After that i have this error : "The server could not be reached. You may want to verify your connection and try again". I try to restart and i have error like i describe in my last comment.
