After I installed solr on my machine to test for upgrade implementation to the latest 9.6.1 version I get no error in starting up solr, however when I access localhost:8983 or localhost:8983/solr/#/ I get ERR_EMPTY_RESPONSE.
The logs look like this:
starting logs:

./solr start

the status is running and I do not see any problem in the logs
I am using java 11 which is the recommended version

I tried reinstalling the tar file and starting solr again.
i increased the open file limit to:

ulimit -n 65000
ulimit -u 65000

I tried allocating more memory to java heap
SOLR_HEAP=”512m”
and SOLR_JAVA_MEM=”-Xms512m -Xmx1g”
i checked the ports and moved solr to 8984 but still the same issue
