SSO configuration with Shibboleth

I am using Windchill PDMLink Release 12.0 and Datecode with CPS 12.0.2.0 With shibboleth installed, after session is timed out the session hook is not maintaining the full URL needed. e.g. starting point: click on any action on displayed PALMA webpage in Edge browser like URL: https://palma.xxxxxx.net:xxxx/Windchill/app/#ptc1/tcomp/infoPage?oid=OR%3Awt.pdmlink.PDMLinkProduct%3A174xxxxx&u8=1 whenever OKTA verification is outdated - system will be forwarded to OKTA for new verification, after verification browser is forwarding back to PALMA but URL is modified like: https://palma.xxxxxxxx.net:xxxx/#ptc1/tcomp/infoPage?oid=OR%3Awt.pdmlink.PDMLinkProduct%3A1743xxxx&u8=1 "/Windchill/app" is missing - result is, that PALMA Apache webserver displays then "it works!" only like calling https://palma.xxxxxx.net:xxxx/
