FAQ

1. How to Handle Errors When Installing Plugins? 安装插件时遇到异常应如何处理？

Issue: If you encounter the error message: plugin verification has been enabled, and the plugin you want to install has a bad signature, how to handle the issue?

Solution: Add the following line to the end of your .env configuration file: FORCE_VERIFYING_SIGNATURE=false Once this field is added, the Dify platform will allow the installation of all plugins that are not listed (and thus not verified) in the Dify Marketplace.

问题描述：安装插件时遇到异常信息：plugin verification has been enabled, and the plugin you want to install has a bad signature，应该如何处理？

解决办法：在 .env 配置文件的末尾添加 FORCE_VERIFYING_SIGNATURE=false 字段即可解决该问题。 添加该字段后，Dify 平台将允许安装所有未在 Dify Marketplace 上架（审核）的插件，可能存在安全隐患。

2. How to install the offline version 如何安装离线版本

Scripting tool for downloading Dify plugin package from Dify Marketplace and Github and repackaging [true] offline package (contains dependencies, no need to be connected to the Internet).

从Dify市场和Github下载Dify插件包并重新打【真】离线包（包含依赖，不需要再联网）的脚本工具。

3. Set up authorization save invalid and no error message 设置授权保存无效且无错误消息

Issue: The set timeout time exceeds the default keepalive timeout of 65 seconds in nginx in Dify.

Solution:

• Solution 1: Modify NGINX_KEEPALIVE_TIMEOUT value in the .env file, for example: NGINX_KEEPALIVE_TIMEOUT=650.
• Solution 2: Modify MCP Servers config, for example: {...., "timeout": 50, "sse_read_timeout": 50}.

问题描述：设置的超时时间超过了Dify中默认的Nginx保持连接的超时时间65秒。

解决办法：

• 方案1：修改 .env 文件中的 NGINX_KEEPALIVE_TIMEOUT 值，如：NGINX_KEEPALIVE_TIMEOUT=650。
• 方案2：修改 MCP 服务配置，例如：{...., "timeout": 50, "sse_read_timeout": 50}。
