#11814 new Bug report

Slow upload over TLS

Reported by: fingust Owned by:
Priority: normal Component: FileZilla Client
Keywords: Slow TLS Cc:
Component version: 3.39.0 Operating system type: Linux
Operating system version: Mint 19 (kernel 4.19.0)

Description

When uploading files while using explicit TLS connection the progress bar in queue log will reach 100% (file uploads) and stay at that point until the connection times out (after whatever amount of seconds I set in the settings). At this point the file is actually transferred (I've tried canceling the process queue and refreshing server listing) but filezilla marks the upload as failed and will retry to upload the same file asking me if I want to rewrite the existing file in the process.

It will do that for every file in the upload queue until it reaches the maximum number of retries.

This only happens on my linux machines and over TLS connection, if I boot windows on any of them, upload over TLS works flawlessly, so I suppose that rules out the server (vsFTPd 3.0.3 with virtual users running on Debian 9.6.0)

Correct ports are open on the server firewall and I've also tried disabling firewalls on both sides, didn't help.

Certificate was generated with certbot software package.

Which version of GnuTLS is FileZilla linked against? You can see this information in the about dialog.

Replying to Tim Kosse:

GnuTLS: 3.5.19

All tho, with further experiments I've ruled out the FileZilla itself.. it seems to be happening only when the traffic is going thru my modem/router which was provided by my ISP. Over my phones hotspot it works fine. The router is Cisco EPC3928S.

Are there any router settings that could cause that? I've already tried changing a bunch of them and also tried hard reset, but no luck.

I don't think it's the ISP itself because the same company provides my phone service, and like I stated before, it worked over phones hotspot. However I am not sure if those two networks are related at all.

What's also interesting is that I've also tried setting up a virtual machine with Virtual Box and it works with NAT network adapter, but not with bridged adapter, which connects to the router directly.

Long story short: It only happens with Linux based OS-es that are directly connected to my router.
