同求啊，我也是这个问题，在文章里面上传图片就是提示网络错误，这是我的日志。。。

Damon-Yo

Ryan Wang 👍 百分百复现，其实文件没什么特殊的，就是一张图片，写文章的时候点击工具栏的上传图片，选中图片之后就是这个错误，随便一张图片都是报网络异常。

liuxiansen

Ryan Wang 👍 偶尔出现附件只是简单的图片这几天上传就是好的我只遇到过一天那一天怎么穿都是网络错误

Ryan Wang 👍

Damon-Yo 麻烦联系我。709831589

Damon-Yo

问题大概清楚了。

主要原因可能是系统执行了 tmp 目录清理服务，导致 /tmp/undertow...8090/ 目录被清理，然而在上传的时候，undertow 服务器需要创建 /tmp/undertow...8090/undertow...upload 临时文件，但是调用 Files.createFile(...) 的时候就会发现找不到父目录，才导致了以上的错误。

已记录。

Damon-Yo

johnniang 请问这个问题是你们在后面发布更新解决，还是我自己百度解决。。。😂

Ryan Wang 👍

Damon-Yo 已经解决了，不过还得等我们发布版本。

现在临时方案是重启 Halo，或者查看日志，创建 /tmp/undertow...8090/undertow...upload 文件夹。

Damon-Yo

Ryan Wang 👍 OK多谢，辛苦
