Pega login fails with CookieDisabledException | PRPC731 and Tomcat.
On intermittent basis,we could find pega portal login failure issues for end users with the below mentioned exception in the logs.
"com.pega.pegarules.priv.context.CookieDisabledException][STACK][com.pega.pegarules.priv.context.CookieDisabledException: An error has occurred which indicates that your browser does not support Cookies. You must enable Cookies in order to use this application."
I am unsure about the issue context, but I would like to give info about the setting.
Functionality: Process Commander sends information between the server and the client (browser) using URLs. These URLs can contain “query strings” which display calls to activities in the system or output streams of data.
PegaRULES typically redirectes guests (unauthenticated requestors) to the standard URL format above in preparation for interactive authentication. Not all authentication schemes(like PRCustom) require this; if your authentication scheme doesn’t require interaction, set this entry to false to reduce network traffic.
Below is the link of the document for reference which contains descriptions about standard config settings.
There is no guide specific to 7.3.1 as the settings mentioned in the 6.x guide is standard and applicable from 5.x to 8.x
JFYI - During or Post-SSO authentication, engine API's will execute and checks if certain redirect request is needed or not and also checks for PegaRULES cookie if it does not exist at the time of redirect, it reports CookieDisabledException.
As you have multiple follow-up queries regarding impact & what's best for 7.3.1, I would strongly recommend you create SR and get it investigated by submitting the entire stackTrace and replication steps, so that we can further evaluate the issue and get the applicable settings based on your use-case.
