You have installed the new Support Package SP28 in you PI/PO 7.5 system.

You start noticing the SFTP channels having some issues like not being able to connect to some SFTP sites using private SSH key as authentication method.

In the XPI 50 you can see the below exceptions:

• "Exception received: java.lang.UnsupportedOperationException: promptPassword(String message) is not implemented yet!"
• "send failed: promptPassword(String message) is not implemented yet!"
• "Caught runtime exception while notifying MonitoringStatusListener com.sap.aii.af.service.administration.impl.AlertingStatusListener@18eece51 of state change: java.lang.NullPointerException: while trying to invoke the method com.sap.aii.af.service.cpa.Channel.getParty() of a null object returned from com.sap.aii.af.service.administration.api.monitoring.ProcessContext.getChannel()"
