Previously, the ntopng integration would connect to any reachable ntopng instance without checking its edition. The integration requires a commercial ntopng edition (Pro or Enterprise) and has never supported the ntopng Community Edition - but pointing it at a Community Edition instance was silently accepted. The connection appeared to succeed, only to produce silent failures or confusing errors later, once a Pro-only API endpoint was queried.
Checkmk now checks the ntopng edition right after authentication and rejects the connection with a clear message if the instance runs the Community Edition.
If the edition can't be determined - for example on an ntopng version that doesn't report it - the check is skipped, so existing valid setups keep working.
Since the Community Edition was never supported, this change doesn't affect any working configuration.
