Authentication failed because the remote party has closed the transport stream

Our company provides a Blackboard LTI integration for several colleges.  This integration imports data from an external curriculum design software into Blackboard using Bb SOAP services (and yes, we're converting over to REST services).

 

One of our client colleges recently upgraded their Bb instance to version Release 3500.7.0-rel.10+58ec50a.  They run the self-hosted Original experience Blackboard.

 

After the upgrade, the calls to Bb SOAP services within the LTI integration stopped working.  We see errors of this type:  Authentication failed because the remote party has closed the transport stream.

 

The college Bb admin and I have reviewed the Bb LTI integration settings, but I don't see anything wrong.

 

Does anyone have any suggestions on what I should look for to fix this problem?  

 

Thank you.
