WinSCP fails to connect

2022-09-13 08:52

I created a .bat script

@echo off
"C:\Program Files (x86)\WinSCP\Winscp.com" /log=example.log /script="C:\SAGE\Specific\FilesReceived\test.txt"

who executes

open sftp://Username:Password@ftp_address
exit

The script works very well but every 6 launches, it gets stuck on the connection and times out.

I tried several configurations but I can't find what's stuck

Isn't it the server that blocks you temporarily for too frequent connections?
At the moment the script cannot connect, can you connect anyhow from the same local machine to the same server (in WinSCP GUI, in any other SFTP client)?
Post logs.

Can you please explain what do the logs represent? You didn't answer my questions either.

I tried to connect in ftp and not sftp and it works perfectly. In sftp every 6th connection I receive a time out.

I tried with several servers and I have the same problem.

The log corresponds to 2 successful connections and the last failed.

I have asked you:

At the moment the script cannot connect, can you connect anyhow from the same local machine to the same server (in WinSCP GUI, in any other SFTP client)?

How long does the period during which you cannot connect lasts?

I can connect from anywhere just fine.

The script misses the 6th connection, the 12th...

if I launch the 6th and immediately the 7th the 6 is waiting for connection and the 7th works.

I hope you can understand that WinSCP does not block every 6th connection for fun. It does not even know that it's 6th connection. WinSCP does not even remember anywhere that its previous instances connected somewhere already, let only how many times.

It must be something external to WinSCP. Firewall, the server itself... Can you open 6 connections in sequence in WinSCP GUI or in any other FTP client?
