Siebel Connector

I am attempting to connect to a clients Siebel server using the built in a!sblInvoke expression. I am however receiving the following error:

[success:false,result:,error:[code:[category:0,namespace:1,detail:0],title:Error calling sblInvoke,message:The external server for this system [key=siebeldev] generated an exception when calling a function [sblInvoke]. Details from external system: <Exception>
<Major No.>16</Major No.><Minor No.>8716488</Minor No.><Message>Could not open a session in 4 attempts. {1}(SBL-JCA-00200)</Message><DetailedMessage>Unknown<DetailedMessage>
</Exception>,detail:Could not open a session in 4 attempts. {1}(SBL-JCA-00200)]]

I have checked the Siebel logs and there is no record of the call or exception. It seems that the call is not even making it to Siebel.

We are using Appian 16.2 and calling Siebel 15.8.0.0.

Has anyone experienced a similar issue?
