I think I found a bug when downloading files from the OttoFMS “FileMaker Server” area.
If you try to download multiple files in rapid succession, the first file will be successful, but sometimes (not 100%, but I was able to make it happen several times in testing) the subsequent files will download with a size of 1KB.
The files were open/hosted, but had no clients connected.
This particular server is running OttoFMS Version: 4.7.2.241024398
Haven’t tested on other servers.
Tested with very small files (<1MB each) and some that are merely regular small ~35MB.
