Hi,
after patching installation with dedicated utility

and after a serveral restart, portal does not respond.
This is what i see in my browser (cache cleaned)

rest respond

but when i navigate in a service...

This is a single machine deployment and I never seen this type of error
Have you any suggestion?
It's a problem similar to this: https://community.esri.com/t5/arcgis-enterprise-portal-questions/portal-10-3-configuration-settings/td-p/761343/page/2
Please help!
Thanks in advance.
