Mac Desktop client data transfer interrupted

Seafile Client
1

Folks I’ve some issues with a Seafile installation running on Docker on NAS behind a reverse proxy.

Seafile is set up on port 8000 going through to 443 on a Synology via their web interface. I can add some advanced variables to tweak things, but I’m new to RPs so don’t really know how to fix this.

I’m connecting via the web interface, and uploading SOME files, like a few small folders, but I’m trying to put up a Joplin folder with 45000 or so very small files in and it gives me the following errors. I also got errors on the smaller folders but it finished syncing after going through the errors, it just resumed the sync and finished.

I’ve been reading the forum a lot but there’s a bunch of stuff about Nginx servers that’s going a bit over my head. I do have some movement to configure the Synology with some advanced settings, so if anybody has some ideas about that I could try and translate them to the Syn interface.

Thanks in advance.

I’ve been at it for the whole day trying to work through this problem.

Seafile works without the reverse proxy in place, synced 4GB of data super fast.

The problem with the Synology is that it locks down ports 443 and 80 for it’s own Nginx RP server, so installing other systems can be a bit of a pain in the arse to configure (switching ports), and you may need to redo that work upon updates, so I’d rather get it configured for the existing software.

The problem with the existing reverse proxy interface is that they don’t allow for much in the way of configuration. You can add some stuff like ‘proxy_pass’, but you can’t add the location /seafhttp config settings.

I’ve ended up changing the nginx config file inside the synology - only problem is that if I open the control panel on synology, it reverts back to how it was before.

I think the Seahub log points to file uploading errors via the browser
