Hi~ @Pedro_Ramalho ,
According to the log you sent, the error is a response from the server stating that the file could not be found. (404 Not Found)
In other words, the issue occurred because the download request returned that the file does not exist.
This issue can have several causes.
One possibility is that the file name is too long.
Depending on the type of server, there are servers that do not work well when the file name or full path is too long.
Another cause is that the characters in the file name do not match what was requested on the server.
In this case, you need to directly connect to the server and check it.
This issue occurs quite differently depending on the type of server, so you need to check the limitations of the server.
Please change the file name to short and try again. If the problem persists, upgrade the server or upgrade RaiDrive to the latest version.
If possible, please send your test account and connection information via email(firstname.lastname@example.org) so that we can connect to and test the server where the issue occurs, and we will connect and test it directly.
