What to do with Memgraph Lab error: Your connection is invalid, please reconnect again.?

I started the Memgraph using docker run -it -p 7687:7687 -p 7444:7444 -p 3000:3000 -v mg_lib:/var/lib/memgraph memgraph/memgraph-platform. I opened a Memgraph Lab using localhost:3000. Then I shutdown the Memgraph, and started it again. In the log I can see the flowing error.

What is this? I didn't change any network settings or ports.

Solution

  • Most probably, you are seeing this error because you have a browser window with Memgraph's UI open and it needs to refresh its connection. Just reconnect all connections.
