> *Explanation*
> * {{IgniteClientConfiguration.DFLT_PORT_RANGE}} is 100.
> * We try all endpoints in random order (because they go into a Map - see initChannelHolders).
> * Default RetryPolicy has retryLimit = 16
> We fail after 16 tries, never checking port 10800.
> *Potential fixes*
> * Reduce default port range (both on client and server)
> * Remove port range from the client completely (controversial feature - other db drivers do not have that)
> * Fix connection logic to try ports in order
> * Increase default retry limit
