My attachment will not upload
Last updated about a month ago
Uploads fail for a small number of reasons, and the error message usually points straight at which one.
Size
The per-file limit is shown underneath the upload box on the ticket form. Files above it are rejected before the upload finishes, which can look like a hang on a slow connection.
File type
Executable files are blocked for security. If you need to send one, put it in a zip archive first.
Connection
Large uploads over an unstable connection can time out part way. Retrying on a wired or stronger Wi-Fi connection usually resolves it.
A reliable workaround
Submit the ticket with no attachment first so you have a ticket number, then reply to that ticket and attach the file. Replies use the same limits but you will not lose the text you have already written if the upload fails.
