SearchApiException while retrieving config files of Solr server solr_server server: "0" Status: Request failed: Permission denied in SearchApiSolrConnection->checkResponse() (line 536 of .../search_api_solr/includes/solr_connection.inc).

With the same links everything worked well in Windows. I'm not sure what permission is missing in Linux and would appreciate any insight on this.
