Hey @andreims, connection issues like “connection refused getsockopt” can be rather annoying. 
Let’s try a few steps to get to the bottom of this.
First, let’s check if the Minecraft server is actually running. You can see the logs by right-clicking on the instance and selecting “View Logs.” Could you post the last part of that log here? (Text only, please; no images or links.)
If everything looks good in the logs, also make sure your server’s IP and port are correctly set.
Once we have the logs, we can delve deeper!
