Hello, i have the the following error when trying to ligin into SAS:
500 Internal Server Error
An error occurred. Please contact your system administrator.
I tried to restart SAS(using the command ansible-playbook viya-ark/playbooks/viya-mmsu/viya-services-start.yml)
but the same error appears.
I looked into a elastic search log :

Could it be a connection error(ports blocked etc) or do I have to restart some services?
