自建NSTBrowser Docker容器后无可用API端点的问题求助

最近我在本地使用app.nstbrowser.io的客户端时一切正常，对应的核心代码片段如下：

import { Proxy } from '@devflexi/proxies';
import { NstBrowserV2 } from 'nstbrowser-sdk-node';
import { chromium } from 'playwright';
import type { Browser, BrowserContext, Page } from 'playwright-core';
import { Protocol } from 'playwright-core/types/protocol.js';
import { NST_BROWSER_API_KEY, NST_BROWSER_URL } from '../../config.js';
import { logger } from '../../logger.js';

const usedProfileIds = new Set<string>();

export class ManagedBrowser {
  public readonly id: string;
  private browser!: Browser;
  private context!: BrowserContext;
  private page!: Page;
  private busy = false;
  private connected = false;
  private client: NstBrowserV2;
  private profileId!: string;

  constructor(id: string) {
    this.id = id;
    this.client = new NstBrowserV2(NST_BROWSER_API_KEY, {
      timeout: 60000,
      apiAddress: `http://${NST_BROWSER_URL}/api/v2`,
    });
  }

  public isBusy(): boolean {
    return this.busy;
  }

  public markBusy(): void {
    this.busy = true;
  }

  public markFree(): void {
    this.busy = false;
  }

  public isAlive(): boolean {
    try {
      return this.connected && this.browser.contexts().length > 0 && !this.page.isClosed();
    } catch {
      return false;
    }
  }

  public getPage(): Page {
    return this.page;
  }

  public getContext(): BrowserContext {
    return this.context;
  }

  public getBrowser(): Browser {
    return this.browser;
  }

  public async connect(): Promise<void> {
    const browserProfiles = await this.client.profiles().getProfiles();
    const profile = browserProfiles.data.docs.find((profile) => !usedProfileIds.has(profile.profileId));

    if (!profile) {
      throw new Error('No available profile found');
    }

    this.profileId = profile.profileId;
    const browser = await this.client.cdpEndpoints().connectBrowser(profile.profileId, {
      headless: false,
      autoClose: true,
      clearCacheOnClose: true,
    });

    this.browser = await chromium.connectOverCDP(browser.data.webSocketDebuggerUrl, { timeout: 15000 });
    const contexts = this.browser.contexts();
    this.context = contexts.length > 0 ? contexts[0] : await this.browser.newContext();
    const existingPages = this.context.pages();
    this.page = existingPages.length > 0 ? existingPages[0] : await this.context.newPage();
    this.connected = true;
  }

  public async setProxy(proxy: Proxy): Promise<void> {
    const cdpClient = await this.page.context().newCDPSession(this.page);
    await cdpClient.send('Network.updateContextProxy' as unknown as keyof Protocol.CommandParameters, {
      proxyServer: `http://${proxy.username}:${proxy.password}@${proxy.host}:${proxy.port.toString()}`,
    });
  }

  public async close(): Promise<void> {
    try {
      await this.client.browsers().stopBrowser(this.profileId);
      logger.debug(`[ManagedBrowser] Closed ${this.id}`);
    } catch (error) {
      logger.error(`[ManagedBrowser] - Error closing ${this.id}:`, error);
    } finally {
      usedProfileIds.delete(this.profileId);
    }
  }
}

本地测试时我设置NST_BROWSER_URL=localhost:8848，代码能正常连接并调用API。

但当我准备部署到生产环境，尝试用官方提供的Docker命令自建NSTBrowser服务时：

docker run -it -e TOKEN=xxx -e PORT=8848 -p 8848:8848 --name nstbrowserless nstbrowser/browserless:latest

容器启动后，我发现所有API端点都无法访问——不管是在宿主机用curl请求，还是进入容器内部执行请求，所有尝试的端点都返回404错误。我已经确认端口映射没有问题，因为容器内测试也同样失败。

有没有朋友遇到过类似的问题？或者知道该如何排查和解决这个API端点不可用的问题？
