First, awesome project! I've been hoping for a self-hosted replacement of smallpdf, this might be it!
Now, I used the docker container for this, and tried to compress a PDF. However, clicking on "Compress" only resulted in a very light download.htm file being downloaded. Here was its content:
<html>
<head><title>413 Request Entity Too Large</title></head>
<body bgcolor="white">
<center><h1>413 Request Entity Too Large</h1></center>
<hr><center>nginx/1.14.2</center>
</body>
</html>
I do not know if this issue also happens if nginx returns any other non-200 return code, but at least for this one, it could be nice to have some message printed on the page, a toast or a pop-up?
Thanks :)
