Port 6619 cannot be used for client authentication, it already blocked by an OFTP channel

[former_member265645]

Hello,

we have oftp connections inside SAP PO 7.5.

Our oftp sender adapters our configured without Client Authentication. But our new OFTP sender adapter should be with Client Authentication. After activating new OFTP sender channel, error occured:

Port 6619 cannot be used for client authentication, it already blocked by an OFTP channel

How can we use OFTP sender adapters "with Client Authentication" and "without Client authentication" same time?

Use client Authentication option is ticked:

Use client Authentication option is not ticked:

Dear Nurhan,

please check this SAP note:

Apparently you cannot use same port for OFTP senders with and without client authentication.

Kind regardsm
