- NAS running QTS / QuTS hero
Overview
A 403 Forbidden error is an HTTP status code indicating that your request was understood by the server, but the server refuses to fulfill it. This typically means your NAS is blocking access from your IP address or network, even though the web server is reachable and the URL exists. Common causes include your IP address being on the deny list or being temporarily blocked due to repeated failed login attempts. Features such as allow/deny lists and IP access protection are designed to strengthen system security.
Occasionally, browser cache or cookies can lead to a 403 error. To rule this out, try accessing your NAS from a different web browser or in Incognito/Private mode.
Solution
- Test browser access:
- Open the NAS login page in a different browser or Incognito/Private mode.
- If accessible, clear your original browser’s cache and cookies and try again.
- Check the allow/deny list settings:
- Go to Control Panel > System > Security > Allow/Deny List.
- Review entries in both lists. If your IP address or range appears in the deny list, select it and click Remove.
- Click Apply to save changes.
- If QuFirewall is installed, open QuFirewall and review or modify the allow/deny settings accordingly. Refer to QuFirewall’s documentation for detailed steps.
- Check IP access protection status:
- If IP access protection is triggered by multiple failed logins, your IP address may be temporarily blocked. To review and unblock, go to Control Panel > System > Security > IP Access Protection and manage the blocked list as needed.
Note: Modifying firewall or security settings may affect system security. Make changes with caution. If you are unable to access your NAS at all, consider using a different trusted network or contact QNAP support for further assistance.

概述
403 Forbidden 错误是一个 HTTP 状态码，表示服务器理解您的请求，但拒绝执行。这通常意味着您的 NAS 正在阻止来自您的 IP 地址或网络的访问，即使网络服务器可达且 URL 存在。常见原因包括您的 IP 地址在拒绝列表中或由于多次登录失败而被暂时阻止。允许 / 拒绝列表和 IP 访问保护等功能旨在增强系统安全性。
有时，浏览器缓存或 cookies 可能导致 403 错误。为排除这种情况，请尝试使用不同的网络浏览器或在隐身 / 私密模式下访问您的 NAS。
解决方案
- 测试浏览器访问：
- 在不同的浏览器或隐身 / 私密模式下打开 NAS 登录页面。
- 如果可以访问，请清除原始浏览器的缓存和 cookies，然后重试。
- 检查允许 / 拒绝列表设置：
- 前往 控制台 > 系统 > 安全 > 允许 / 拒绝列表。
- 查看两个列表中的条目。如果您的 IP 地址或范围出现在拒绝列表中，选择它并点击 移除。
- 点击 应用 以保存更改。
- 如果安装了 QuFirewall，打开 QuFirewall 并相应地查看或修改允许 / 拒绝设置。有关详细步骤，请参阅 QuFirewall 的文档。
- 检查 IP 访问保护状态：
- 如果 IP 访问保护因多次登录失败而被触发，您的 IP 地址可能会被暂时阻止。要查看和解除阻止，请前往 控制台 > 系统 > 安全 > IP 访问保护 并根据需要管理阻止列表。
注意： 修改防火墙或安全设置可能会影响系统安全性。请谨慎进行更改。如果您无法访问 NAS，请考虑使用其他受信任的网络或联系 QNAP 支持以获得进一步帮助。
