Below are some scenarios you may encounter and their solutions.

If you having trouble installing the proxy server, you can also install it manually. To do so:

1. Create a folder if it does not exist named ext in the GrassClipper folder.
2. Download and extract the contents of this file into the ext folder
3. Double click mitmdump.exe and allow it to run for a few seconds to generate the certificate
4. Run this command as Administrator: certutil -addstore root "%USERPROFILE%\.mitmproxy\mitmproxy-ca-cert.cer"
5. Use GrassClipper like normal!

Encountering a white screen? Ensure WebView2 is installed

You may also want to run this command as administrator: CheckNetIsolation.exe LoopbackExempt -a -n="Microsoft.Win32WebViewHost_cw5n1h2txyewy"

If you have Chinese characters in your file path, this may crash it too! I am working on a fix.

You can also try running in Windows 8 compatitbility mode.

If all else fails, you can run GrassClipper in chrome or browser mode. To do so:

• Create a shortcut to GrassClipper.exe
• Right click the shortcut, click properties
• In the Target box, at the very end, add --mode=chrome or --mode=browser
  • chrome only works if you have Chrome installed, and will create a Chrome window
  • brower will, you guessed it, open GrassClipper in your default browser
• Click Ok
• Run GrassClipper using this shortcut from now on!

You may be using the wrong port, ensure your port in GrassClipper is either 443 or nothing (not 0, but literally nothing)

1. If you are running a local server, ensure the local server is running. Otherwise, ensure the server you are connecting to is actually running.

2. If you are able, use the development branch of Grasscutter. It is known to work better with GrassClipper.

If you are still getting an error 502 when attempting to log in to your own server, open your Grasscutter config and add the following to the DispatchServer section:

"PublicPort": YOUR_PORT

where YOUR_PORT is the same port you use as the Port value already. This will probably be 443.

Ensure you have the correct keystore.p12 file that comes with your branch (stable or development). Also ensure the password is set properly in Grasscutters config.json (blank for stable, "123456" for development).

If you are getting infinite CMD windows for any of the scripts (such as the proxy installation, or private server start), ensure you have UAC (user access control) set to any option that requires asking. Ensure your user account can open things as Admin.

Discord/YouTube (plus surely some others) does not seem to be a fan of the proxy server. You may need to disable it by either closing mitmdump or by disabling your proxy in the Windows proxy settings.

The launcher most likely did not close correctly, and was unable to clean your proxy settings back to what they were. Disable your proxy in the Windows proxy settings.
