i do not know what happened but I am not able to log in to UserApp anymore. I am able to log in to SSPR, to iManager as uadmin but UserApp (IDMProv/landing page, dash,...) does not work.
I see that an assertion is sent in the catalina.out and in the browser, I just see the spinning wheel only in the blank page.
After few minutes the error below occurs:

Do you have any idea what's wrong? I already tried to reinstall/update SAML nmas method, double checked the configurations, changed the authentication to the another eDIR in the replica ring, but nothing helps.

Thanks for your support in advance!
