IOException occurred when talking to Solr server

Caused by: org.apache.solr.client.solrj.SolrServerException: IOException occurred when talking to server at: http://localsolr:8983:8983/solr

This was likely caused by a library version change. This is a result of the SOLR_HOST variable including a port e.g. SOLR_HOST: 'localhost:8983'.

To resolve this, remove the port from the SOLR_HOST variable in your docker-compose file. If the 8983 port is not desired, set the SOLR_PORT environment variable to the desired value.
