You may be missing some sort of configuration. Make sure following is set according your environment and network setup:

If using windows, update the solr.in.cmd:

############ Considering solr and alfresco are setup on same machine. Update the host config as per your setup. This is an example.

set SOLR_SOLR_HOST=localhost
set SOLR_SOLR_PORT=8983
set SOLR_SOLR_BASEURL=/solr
set SOLR_ALFRESCO_HOST=localhost
set SOLR_ALFRESCO_PORT=8080
set SOLR_ALFRESCO_BASEURL=/alfresco

:: Since we are setting up with no SSL, this property need to be set to none. Default is https
set SOLR_ALFRESCO_SECURECOMMS=none

If using linux, update the solr.in.sh:

############ Considering solr and alfresco are setup on same machine. Update the host config as per your setup. This is an example.

SOLR_SOLR_HOST=localhost
SOLR_SOLR_PORT=8983
SOLR_SOLR_BASEURL=/solr
SOLR_ALFRESCO_HOST=localhost
SOLR_ALFRESCO_PORT=8080
SOLR_ALFRESCO_BASEURL=/alfresco

:: Since we are setting up with no SSL, this property need to be set to none. Default is https
SOLR_ALFRESCO_SECURECOMMS=none

Update the alfresco-global.properties:

############ Considering solr and alfresco are setup on same machine. Update the host config as per your setup. This is an example.

# Set this property unless you have explicitly chosen to expose some repository APIs without authentication
solr.host=localhost
solr.port=8983
#none, https
solr.secureComms=none
solr.base.url=/solr
index.subsystem.name=solr6

You can find detailed steps here, please cross check all the configurations.
