Solr cant initialize keystore

[Mei]

I'm trying to install Alfresco Search Services using this  guide. I've generated secure keys for SLL communitacion with this  tool and then moved them to <SOLR_HOME>/keystore.

Then I've made configurations in:

<SOLR_HOME>/templates/rerank/conf/solrcore.properties:

# solrcore.properties - used in solrconfig.xml
#

enable.alfresco.tracking=true

#
#These are replaced by the admin handler
#

#data.dir.store=workspace/SpacesStore
#alfresco.stores=workspace://SpacesStore

But I get this error:

It basically says, that my defined path for keystore points to a directory instead of a file which makes no sense to me. I've tried to move the keystore file in other directories or use configuration with some random path, but I always get this same error so it seems that "alfresco.encryption.ssl.keystore.location" in "solrcore.properties" has no impact on this error. I wonder if there is some wrong configuration in my files or some other problem, but I've double checked every step from the guide and I'm stucked now. I will be very grateful for any help.
