Time to time its giving error in the FTP connection

[Former Member]

Hi Gurus,

Im doing File to File Interface. Im using FTP for File transfer and the message protocol is 'File'. Im using the connection security as 'FTPS(FTP Using SSL/TLS) for control and data connection' and set the default command order.

I have uploaded the required certificate in the FTP server and the XI server also. I can view the certificate in the keystore of visual Administrator. Its working fine. But the problem is time to time its giveing this error "Error occurred while connecting to the FTP server "170.135.128.149:20021": iaik.security.ssl.SSLCertificateException: Peer certificate rejected by ChainVerifier"

Can anyone please help to resolve this issue. i need to fix it as soon as possible.

Rama,

Did you tried to connect the FTP site using FTP tool like FTP WS-PRO?? where you can set same setting and certificate.

Also check if you have maintained server name entry in host.ini file on the system where adapter engine is host.

Hope this will help.

Hi All,

Thanks for your replies.

I have verified all the settings mentioned in the sap note. I could not figure out the problem.

When delivering the file to the receiver in the first time always failing. When it retries, its delivering successfully. What could be the probelm when delivering first time. The error message is 'Attempt to process file failed with iaik.security.ssl.SSLCertificateException: Peer certificate rejected by ChainVerifier'. Is anything need to verify in the FTP server side. Im using passive connection in the Communication channel.

Plz can anyone tell y it is failing in the first time alone.

Hi All,

I m facing one peculiar problem with FTP server. I have desinged one R3 to FTP interface. I m trying to connect to FTP with secure SSL connection. For that we uploaded the certificate in the FTP as well as in the Visual administartor in the XI box. I didnt create any SSL socket for this. Our basis team told like we dont need this SSL socket stuff because here we are using FTP as a client. So just they uploaded the certificate in the trusted CA of Visual administartor. Our certificate is obtained from verisign. So the CN name in the certificate is Verisign. I didnt find any thing in the certificate other then this. In our communication channel we gave the hostname instead of IP address. But here my problem is, When i send the file to FTP its giving error in the first attempt. After that the message retiried itslef, the file has been sent successfull in the retry process. Why it is always fails in the first attempt.

Can anyone please help me to resolve this. I need to be fix today itself.

Hi Ganeshan,

Can you give a try by changing the IP address to a fully qualified domain name and see you run into same issues or not. Also please check this thread:
