Upgrade to Washington DC and the SSO stopped working

[Snow Tomcal]

Hi, 
we have a self hosted environment. 
We upgraded yesterday our Development instance to Washington DC Patch 8 Hotfix 3 and the SSO is no longer Working.
we are using costume OIDC, and everything was working fine before. |
Does anyone know how to resolve this issue?

Customers can break xmlstats.do for ServiceNow, causing outages, if they remove the "public" role from the AAdminProcessor.execute ACL

Hi,

what you sent does not seem to be related to the SSO.

Hi @Snow Tomcal 

I am no sure that OIDC come with plugin, if yes, try to repair or update it. else log a Now support case.
