When failed to proxy pass with https in Quasar framework, it is very likely that the target-host HTTPS are configured incorrectly. As a workaround, you can modify the quasar.conf.js with secure:false as following:
"/context/path1/": {
target: "https://target-host/path1/",
secure: false,
changeOrigin: true,
pathRewrite: {
"^/context/path1/": "",
},
},
