Some questions

[HtnrxUNc]

Hello, contributors. I've encountered some very strange problems so far, some of which I've found answers to, and some of which I haven't found solutions to at the moment, so if you have solutions to these problems, you can reply to me here. First of all, the environment I am using

Operating Environment

---

• ubuntu 20.04TLS (for the server side, in VMware's virtualization. But ubuntu itself uses the desktop side, i.e. ubuntu with its own desktop).
• Both mongodb and Python are running in docker, and at the moment I can't access them via ./mongo --version etc. to get valid version information.
• Both JDK and JRE versions are 17

Catalog Usage

---

• Grasscutter
  • data (The data directory holds the data directory/files for the dev branch)
  • keys (The keys directory holds the keys directory/ or files for the dev branch)
  • keystore.p12 (keystore.p12 from dev branch)
  • grasscutter.jar
  • proxy.py (proxy.py from dev branch)
  • proxy_config.py (proxy_config.py from dev branch)
  • resources (The resources directory holds all the files of the GenshinData project)
  • BinOutput (The BinOutput directory holds all the files of the gi-bin-output project)
  • proto (The /resources/proto directory holds all the files of the Grasscutter-Protos project)
  • ExcelBinOutput
  • Readable
  • Subtitle
  • TextMap

config

---

• in the configuration file
  • PublicIp values are all ubuntu ip
  • The game port is 22102
  • Login port is 443
  • KeystorePassword is 123456
  • AutomaticallyCreateAccounts is true

proxy_config.py

USE_SSL = True
REMOTE_HOST = "127.0.0.1"
REMOTE_PORT = 444

I use Mitmproxy to hijack traffic

Some of the problems I have encountered

---

• I can't log in via ipv4 (currently my server and client are on the same LAN) until I use Fiddler to hijack the traffic to the server's ipv6 address
• My port was not working, which prevented me from logging in. It wasn't until I turned on ubuntu's ufw that the problem was solved.
• When I try to run the jar file, I am prompted that the address is used. I tried using the lsof command and looked at port 443 80 8080 8888 22102 and found that it seemed to be occupied by one of docker's processes. I killed them and the jar file ran successfully.
• When I use Fiddler traffic hijacking locally to ubuntu and Mitmproxy traffic hijacking on the server side as well. And the lawn mower is working fine. I found the game prompting me with error 4206. I tried to get ubuntu and windows to trust two certificates and they succeeded in trusting them. But still prompted me with 4206 error. Until I changed the DispatchServer.PublicIp in the config file to dispatchcnglobal.yuanshen.com. When I enter the game he prompts me for a new update and downloads it automatically. When it finished downloading automatically, I was able to enter the game. But when I close the server and return to DispatchServer.PublicIp, I get 4206 again.(so should this issue be considered unresolved?)

Update I am currently unable to connect to my own server again, once I open the game it connects to the official server. I'm currently looking for the reason and it seems that Fiddler is not intercepting any traffic.

I managed to connect to my server again, but this time I didn't get into the game. The game prompted me Server connection failed. I found the prompt on my server side.

I have found the reason for this problem. Because I changed my network environment, which caused the IP address of ubuntu and windows to change. And the GameServer.PublicIp in the config file was not updated, so the server refused to connect.
