[Former Member]

I am dealing with a scenario that PI sending message to a FTP server. but failed with below log error:

I have tried using FTP tool(CoreFTP) to connect to this target FTP server and succeeded, but why PI get this issue?

Could anyone suggest the reason of this and how to resolve it?

Thanks a lot.

Thanks all of your valuable input!

Actually it is because -- I set the FTP server with SSL but PI doesn;t installed the related SSL certificate.

After  changing the FTPS to FTP, and remove SSL in PI channel, it succeeded.

HI Hailong,

Did you install the related SLL certificate only in the TrustedCA tab of Visual Admin?

HI Hailong,

You might know but it is worth mentioning here...

In order for SAP PI to deal with an folder / drive using FTP adapter, an important pre-requisite is to enable FTP service on required folder / drive. What i mean is lets say you are dealing with /tmp drive on XX.XX.XX.XX IP....then it is necessary that FTP service is running on this IP..

At the face issue seems to be that FTP service is not running on the drive / folder you are trying to deal with. You can confirm this with team maintaining your target location.  In case this is a Windows location, they have to configure FTP with standard means.

Can you please check this and and come back,,

Thanks..

regards,

Omkar.

If that works fine, then try stop and restart the FTP comm channel.
