Stuck in loop when downloading some files

[lostinspace]

Trying to backup my Wordpress site, and some files get stuck in an eternal loop according to the log below (providing the last three loops). I'm transferring from my web hotel provider. Using FileZilla client 3.47.2.1.

Is this related to the pinned ECONNABORTED topic? If so, what can I do to make it work? And why does it occur for some files only?

Which FTP server software (product and version) is running on the server machine?

[lostinspace]

It's a Linux/Apache server, running PHP 7.2.9.

I don't know which FTP software is running on the server, it's run by my web hotel, Binero. Don't know how to find out, but I have sent a support mail asking them.

I solved the problem by reverting to FileZilla client 3.1.1. Not really a solution, I know.
