Changing host doesn't work sometimes

[wodash]

Sometimes changing the node and its corresponding index doesn't work.

Steps:

1. Install the plugin in a node : 192.168.x.x
2. Run the plugin from 192.168.x.x - At this point shards in this node will be loaded
3. Change the host to 192.168.x.y and choose a Index - At this point shards in the new node (host) will be loaded
4. Refresh the browser - at this point the host 192.168.x.x will be loaded again, but the shards are not loaded
5. now change the host to 192.168.x.y - at this point nothing works.
