 # Quick Troubleshooting
-* If compiling wasnt successful, please check your JDK installation (must be JDK 8 and validated JDK's bin PATH variable)
-* My client doesn't connect, doesn't login, 4206, etc... - Mostly your proxy daemon setup is the issue, if using Fiddler make sure it running on another port except 8888

 * Startup sequence: Mongodb > Grasscutter > Proxy daemon (mitmdump, fiddler, etc.) > Client
-* If `4206` error constantly prompt up, try to use [jdk-8u202-b08](https://mirrors.huaweicloud.com/java/jdk/8u202-b08/) instead of other versions of JDK
