Desktop large attachment sync error to Joplin Server

Hi Everyone,

This is my first posting so I would like to thank everyone for their amazing work - especially Laurent!

I am seeing sync errors on the Windows and Linux beta clients that are Joplin Server-synced for attachments larger than about 20Mb.

The messages on the sync error page have this form:

My Mate Manners - 20190408 - (ab2702a244100fed72865510d4a9347c): Request timed out. Timeout value: undefinedms.

There are no problems on the Android beta or on the release desktop clients (e.g. Linux 2.14.20). Encryption is disabled.

The version are:

  • Android client: 3.0.2
  • Windows and Linux clients: 3.0.6
  • Joplin Server: 2.14.2-Beta (behind NGINX reverse-proxy)

Please let me know if there is any other information I can provide!
