Uploading medium size files fails

[geotheory]

I'm running latest Nextcloud13 on Apache2.4 on Ubuntu 16.04, with no data folder encryption. I can upload very small files (including drag-drop with Dropit) but find anything over ~3 Mb gets stuck on the Uploading.. bar:

I can't think why this would fail for such small files. In my settings it reads Upload max size: 511 MB. I'm just uploading single file, not a batch. Any suggestions?

Perhaps linked to Max Execution Time: 3600?

GitMate.io thinks possibly related issues are #8954 (Uploading large files fails), #1371 (No file-uploading possible at all), #6058 (setup max upload file limited failed), #2090 (Add max share size to public upload), and #5031 (Wrong or no sizes of files/folders).

Thank you my kind bot, but I don't think think so. I've added desktop client and tried syncing. It fails with the following log entry:
