Exception: Failed to decrypt XML element

[Sorin Gheorghiu]

Hi,

we use SSP 2.3.5 for Mediawiki authentication with both LTS 1.39 and
1.43 versions, both using PHP 8.1.31, all SP's are configured similar
and connected to the same IDP, but recently some SP's started to return
the error:

SimpleSAML\Error\Error: UNHANDLEDEXCEPTION

What is the cause of it?
