两天前我在 Manjaro / ArchLinux 中安装了 GNS3 2.1.16，今天我尝试配置它，但出现此错误。

WaitForConnectionWorker thread stopping with an error: Could not connect to 127.0.0.1 on port 3090: [Errno 111] Conexión rehusada
Could not connect to 127.0.0.1 on port 3090: [Errno 111] Conexión rehusada

我尝试为其他人更改端口：3091、3099 和其他人，但它根本没有帮助。出于这个原因，我认为端口 3090 很忙。然后我使用以下命令来验证它。

ss -anp | grep 3090

执行命令时输出

而且港口不忙。我允许自己向您展示在 GNS3 中标记我的错误：

我已经回答了我的问题。

脚步：

  1. 验证正在使用哪个版本的 aiohttp。在我的情况下，版本必须是 ** aiohttp <2.4.0> **，而我的版本是 ** aiohttp <3.5.x> **。由于这个原因，它是不兼容的。

  2. 验证gns3-server和gns3-gui是否为同一版本。

[user@Manhattan ~]$ gns3 --v
2.1.16
[user@Manhattan ~]$ gns3server --v
2.1.16
  1. 如果gns3-server或gns3-gui不一样，我们只需更新包。为此，我们使用以下命令。
> sudo pip3 install gns3-server==2.1.16

或者

> sudo pip3 install gns3-gui==2.1.16
  1. 我们验证 aiohttp 的版本。
> pip3 list
