Handshake between Omeka and Solr not happening

we can successfully install solr (either 6.3 or 4.10 versions) and have solr successfully load the omeka core for SolrSearch plugin.

But omeka just keep reporting “invalid path” when trying to make the hand shake.

We have tried with both jetty and tomcat.

No luck.

Here is the link to a git forum where this solr installation issue is discussed:
