飞牛OS布署seafile13 pro成功，但onlyoffice无法使用
布署容器：
COMPOSE_FILE=‘mariadb.yml,redis.yml,seafile-server.yml,caddy.yml,thumbnail-server.yml,seadoc.yml,elasticsearch.yml,onlyoffice.yml,md-server.yml’
全部容器成功运行
seafile访问ip端口:http://192.168.1.4:9000，能够正常访问网页，正常上传、下载文件
onlyoffice访问ip端口:http://192.168.1.4:9090，能够正常访问网页
已经按要求修改seahub_settings.py配置内容如下：
#添加onlyoffice在线协同编辑
ENABLE_ONLYOFFICE = True
VERIFY_ONLYOFFICE_CERTIFICATE = False
修改为实际IP+端口
ONLYOFFICE_APIJS_URL = ‘http://192.168.1.4:9090/web-apps/apps/api/documents/api.js’
修改为.env中的ONLYOFFICE_JWT_SECRET一样即可
ONLYOFFICE_JWT_SECRET = ‘涉及隐私不显示’
说明：
以下两个配置项无需显式设置，它们有默认值。
如果有自定义需求，可以覆盖默认配置。
ONLYOFFICE_FILE_EXTENSION = (‘doc’, ‘docx’, ‘ppt’, ‘pptx’, ‘xls’, ‘xlsx’, ‘odt’, ‘fodt’, ‘odp’, ‘fodp’, ‘ods’, ‘fods’, ‘ppsx’, ‘pps’, ‘csv’)
ONLYOFFICE_EDIT_FILE_EXTENSION = (‘doc’,‘docx’, ‘pptx’, ‘ppt’,‘xls’,‘xlsx’, ‘csv’)
OFFICE_PREVIEW_MAX_SIZE = 800 * 1024 * 1024 # 预览大小上限，300MB，此选项13.0版本启用
#添加元数据服务（Metadata Server）
ENABLE_METADATA_MANAGEMENT = True
METADATA_SERVER_URL = ‘http://seafile-md-server:8084’
#开启视频缩略图（thumbnail server）
ENABLE_VIDEO_THUMBNAIL = True
txt、pdf文件能够正常预览，但是打开word、excel文件就无法预览
查看onlyoffice容器日志，出现以下报错内容（节选）
