Splunk Add-on for Tenable: Why am I getting error "REST ERROR[1021]: Fail to decrypt the encrypted credential information" after adding a new Nessus input?

[perfecto25]

Current Application: Splunk Add-on for Tenable
App Version
5.1.1
App Build
2

Splunk Version
6.5.2
Splunk Build
67571ef4b87d

I upgraded the Splunk Add-on for Tenable to the current version. When adding a new Nessus Input, Splunk is not ingesting any data from Nessus.

Based on the logs, the problem seems to be a change in the way set-cookie format is being implemented

Fail to load endpoint "global_settings" - Unspecified internal server error. reason={"messages":[{"type":"ERROR","text":"External handler failed with code '1' and output: 'REST ERROR[1021]: Fail to decrypt the encrypted credential information - not well-formed (invalid token): line 33, column 37'. See splunkd.log for stderr output."}]}
