Connection drops after an arbitrary process with Windows 10

Hello all.

First of all, I want to state that I'm using Windows 10 Home.

Here is what I experience. I had set up a database at my home, and connect my PC to my VPS via openvpn protocol. Installed database system is InfluxDB with Chronograf and Grafana. I'm connecting to those services by entering, say, 192.168.1.35:3000 for Grafana within Chrome as it serves as a dashboard for InfluxDB. When I send a query from Grafana (or Chronograf) my connection suddenly drops and says it's been refused. Same thing happens with SSH too. It simply shows an error with a message that says "Connection refused". After sometime, I can connect to anything and my PC does not refuse my connection. However, when I try to query something my connection begins to be refused again.

Before you ask, I already tried adding inbound and outbound rules for the ports, shutting down firewalls completely and adding ufw exceptions at the VPS.

This is just an observation, I couldn't probe the root cause. Any help is appreciated!

    Hi, it seem a race condition, you should look at the %CPU your query use and the available ressource your PC have. If it hit 100% your connection will start to drop as the computer can't continue to answer you.

    Thanks

    Hi ,

    It seems that your environment involves many third-party products which we are not familiar with. Please understand, we are mainly focus on Microsoft products like windows RRAS VPN.

    You might contact the vendor of third-party to do further troubleshooting. If they can narrow down the issue is related with windows system, then I would suggest you open a case with Microsoft to do in-depth investigation.

    Since your environment is complex, we might need to trace some logs to find the cause. However, analysis of log is beyond our forum support level and due to forum security policy, we have no such channel to collect user log information. So we recommend you open a case with MS Professional tech support service, they will help you open a phone or email case to Microsoft, so that you would get a technical support on a one-to-one basis while ensuring private information.

    Best Regards,
