您好，错误4表示下载文件时出现问题：ONLYOFFICE API 文档 - 转换 API
请检查文件路径是否正确。 另外，请从安装Document Server的机器查文件存储的访问。
如果查这些以后还是没找到问题的错在，请重现此问题并发给我们Document Server日志文件 (/var/log/onlyoffice/documentserver, 为Docker 在容器内)
Hello, error 4 means that there was some issue when downloading the file: ONLYOFFICE API 文档 - 转换 API
Please check the path to the file is correct. Also, check the availability of the file storage with the converted file from the machine with Document Server installed.
If you still won’t find the cause of the problem after checking these, please reproduce the issue and send us the Document Server logs file (/var/log/onlyoffice/documentserver, for Docker in the container)
好的，谢谢您的解答，问题已经解决
