Hi,

Our major user complains the upload links fail to work for users. This time I actually found something in the logs to support her claims.

2019-06-12 14:30:29 user shares public upload folder.

[2019-06-12 12:08:03]:COMMAND [ 669] - GET /public/op/<id name>/check-upload?file=filename.pdf&size=62622525&cd=%2F&relPath= HTTP/1.1

 

It tries under different sockets to connect

[2019-06-12 12:08:13]:COMMAND [ 669] -
[2019-06-12 12:08:13]: ERROR [ 669] - Unable to open file 'E:\<path>\filename.pdf' for upload: The system cannot find the path specified.
[2019-06-12 12:08:13]:CONNECT [ 669] - The connection is closed
[2019-06-12 12:08:13]:CONNECT [ 669] - Connection terminated

[2019-06-12 12:08:13]:CONNECT [ 666] - Connection terminated

until:

I can upload large files without any problems. There's space on the drive. I don't know what else to check on my side. Suggestions?

  At first look, I would ask the client does their firewall restrict uploads of certain file size? Do smaller files work for this client?

  It very likely especially if no other users are experiencing this issue, it's something between the client and server causing this behavior.

  I've checked with the remote users. They report they get kicked off before they start to upload the file. 

  I've had other users report problems with links too. They all work from internal network.
