Diagnostics help you determine if there are any issues with the connection. For example, if you see the message “The root resource is not available”, it means that the user credentials are incorrect or this user does not have permissions to view the Web GIS.

Issues uploading data#

Cannot overwrite a layer#

Error message: “Not implemented for feature versioning. This operation cannot be performed on a resource with feature versioning enabled. Disable feature versioning for the resource first, and then try again”.

This means you’re using an outdated version of NextGIS Connect. Please upgrade in Plugins - Manage and install plugins.

Maximum number of resources reached#

Error “Maximum number of resources reached” can occur if your Web GIS is on Free plan and the number of layers is limited to 15. To upload more layers, switch to Premium in your NextGIS ID account.
