oncedoc 硬件版本，安装官网最新2988版本后，无法使用原来的隧穿服务.

操作：

1. 将之前/onceai备份为了/onceaibak

2.按照教程安装了2988版本/onceai目录

3. 将/onceaibak中的 /onceaibak/oncedoc/mod/onceair目录copy回到/onceai/oncedoc/mod/onceair

4. 在/onceai/oncedoc目录下的USER_CONFIG文件中添加了onceair

5.在/onceai/oncedoc目录下的config中module——required部分添加了onceair

6.reboot

问题：

无法打开onceair隧穿功能。

（另外，查看onceair目录中的onceair.js，其中有验证license部分，是否该处与2988版本存在兼容问题。）
