I have a scheduled job to perform secure file transfers daily through WinSCP. The flow starts with 2 ssrs file share subscriptions which drops 2 files in a local directory. Then the sql server agent job I scheduled kicks off a powershell script which initiates the winscp sftp transfer of the 2 files to the remote SFTP server.
The job and file transfers were all working fine and dandy for 2 months until randomly last week when the job started failing on some days but not others. The logs show a cryptic network error "Software caused connection abort". None of these fixed the problem.
And oddly the file transfer is not consistently failing every day. Running the job repeatedly same code fails usually but occasionally succeeds see powershell screenshot attached.
If anyone is familiar with how to fix this issue please let me know. See log entry and powershell screenshot attached. Answer: Being that this was a server-side issue, this item has no immediate solution.
The solution is to confirm with the other party that their SFTP server is configured properly becuause the client-side requests are being initiated properly. Learn more. Asked 11 months ago.

Can you share a log file? Is there possibly some problem with the remote SFTP server itself? It indeed looks like a server-side or network problem. It definitely does not look like a programming question now.
Network error: Connection refused
It only takes a minute to sign up. I have an Ubuntu Server The problem is, sometimes I'm able to login seamlessly. However, sometimes it gives me an error like this: Network error: Connection refused. Then, I dont't change anything, try to login a few times more, wait a while and try again.
Why is WinSCP not able to connect to a server, when other clients are?
Sometimes I can log in, sometimes I cannot. It seems pretty random to me. And Sometimes, Putty gives Network error: Software caused connection abort error after displaying login as: text. I turned off firewall of router, and everything seems to work now.
You must install openssh-server on Linux before this will work. Although if you don't intend to SSH from outside your network, this is not required.

After reading the answers above I suspected an IP address conflict, but needed to prove that address conflict was or was not the problem. This great article showed how to use arp-scan to see if two pieces of hardware were claiming the same IP address.
In my case the server machine had a static ip address of Sure enough there was a conflict, as shown above. Then I ran arp-scan without the grep, found that.
Use arping on the IP address that is having connection issues. I had the same problem, even though I had a static IP address. Turns out another server on my network had been assigned the same static IP address. So it does appear that the problem is caused by IP address conflicts, but there may be various possible ways they can happen.
If you set yours to static and still have a problem, try shutting down your machine and pinging the address. If you get any replies, start looking for what else could have the same address. If so try changing the cables. I can confirm this exact issue: It's not a simple connectivity issue.
The ethernet link does not change state; server is reachable via ping; ssh connects flawlessly occasionally, then seemingly randomly does not connect or existing ssh session drops. This occurs on Ubuntu Following hheimbuerger's suggestion I gave the server a static IP, this seemed to fix it. You might want to check your iptables rules on your server. It sounds like you've a rule for limiting new SSH connections. The next rule allows 5 new connections per minute, if you exceed this limit, your new connections will be rejected after some time has passed:.
I had exactly the same issue, and in my case it turned out to be an IP address conflict. So they don't always agree. I set the router to revoke all the leases by telling it to give only 1-hour leases.Ubuntu Forums Code of Conduct. Results 1 to 6 of 6. February 6th, 1. Join Date Jan Beans 6.

Usually, Network error: Connection refused means that the server refused your SSH connection entirely. It didn't have a problem with the key PuTTY used with it because it didn't get that far in the connection process to even bother with keys. Instead, it refused the connection immediately. This is usually due to the server not running an SSH server or the SSH server being brokenyou having the wrong port, or you having the wrong server address.
However, you say that you only receive that error message when connecting using a public key while connecting using a password works fine. This is a bit different format of the keys. Proper way to convert one to the other is to use ssh-keygen :. Therefore on the single line with key identifier ssh-rsainstead of the one you used. Also the newlines matter there can be none. Install the openssh-server package from Ubuntu Software Center.
Once installed, the SSH service should be started automatically. If necessary, you can start or stop, restart the service manually via command:. Port number 22 is default.
