FileZilla Forums

Hello,
I've just reinstalled Filezilla, because the uploaded files are truncated.
I used the tutorial "Assistant de configuration réseau" , and I got this message, after the test : "Impossible de créer un socket d'écoute sur le port 0, abandon.
Connexion interrompue".
It seems that there is a problem with Avast Web agent or Windows 10 Defender...
Can somebody help me ?
Thanks in advance.

Which protocol are you using to connect to the server?

Sorry, I just see your post now.
I use FTP/TLS

I must add that there is a relation with a disconnection : a part of the file is uploaded (about 32 Kb), then there is a deconnection. After some seconds, there is a second try to send, then a deconnection, and so on.
After a certain time, I am asked "Do you want to replace ... ?" If I answer "Reprendre (retry ?)", the process goes on and at end, the file is uploaded.
