[HPM] Error occurred while trying to proxy request using vpn on windows

Hello, I’m using react app on localhost:3000 which is proxying to our backend server via OpenConnect vpn. My setup is on windows machine and everything worked fine until some moment when I was doing npm start I’ve started getting
“[HPM] Error occurred while trying to proxy request … (ENOTFOUND)” errors. The strange things started here - the backend is reachable and opens without any problem in browser, and restarting my PC is actually helping me to solve this problem, however, reloading PC on every occurrence of this error seems snot very good 😃

My guess it’s something with windows settings, or maybe with VPN connections in the system, I thought maybe someone encountered with the same thing and can give me a hint

I get similar error when requesting my proxy server (node.js v14.15.1 + express): Error occured while trying to proxy to: <hostname> Response code: 500. Here is my code:

app.use('/api', createProxyMiddleware({
    target: API_SERVICE_URL,
    pathRewrite: {
        [`^/api`]: '',
    },
}));
