Disable error display in your wp-config.php and in your php.ini and try downloading it again
I am very sorry, but it doesn’t help.
Can you open the corrupted file in a text editor and see if you any readable text?
not really. But I found a error log (sys.log)
2018/12/23 04:13:43 [error] 4526#4526: *2431 upstream prematurely closed connection while reading upstream, client: <XXX.XXX.XXX.XXX>, server: _, request: “GET /wp-content/plugins/file-away/lib/cls/class.fileaway_downloader.php?fileaway=LXtgooyVNscjn1Qrgv8D1gE%2BmUuSBrQxhopf%2BUQbX8Xyq4mJqVUlOa1%2FOeqqDOyOh1ccTvZcYBwgMXRgs9WV0u449VXXBpJDE8jEWW9XSW2zb89etuyBtjlC9LqXxJjh&nonce=1295b8acf7 HTTP/1.1”, upstream: “http://127.0.0.1:915/wp-content/plugins/file-away/lib/cls/class.fileaway_downloader.php?fileaway=LXtgooyVNscjn1Qrgv8D1gE%2BmUuSBrQxhopf%2BUQbX8Xyq4mJqVUlOa1%2FOeqqDOyOh1ccTvZcYBwgMXRgs9WV0u449VXXBpJDE8jEWW9XSW2zb89etuyBtjlC9LqXxJjh&nonce=1295b8acf7”, host: “www.<domain-name>.de”, referrer: “https://www.<domain-name>.de/konto/drive/”
Maybe this is helpful?
That’s going to be a server configuration issue. I would just google “upstream prematurely closed connection while reading upstream” and see what help you can find.
Hey, finally I found the bug!
My theme used a function callback($buffer) that (why ever) makes the files useless.
Now the error is gone.
So thank you for your time! I will give the theme author a kick in the ass 😉
