Hi, My elasticsearch instance was working just fine, I made some changes to elasticsearch.yml file for email setting and restarted service, but elasticsearch failed to start and I could not even connect to elasticsearch using curl on by ubuntu machine it says failed to connect both on localhost and on IP. I removed changes and restart service but still it failed to start. ```auto elasticsearch.service - Elasticsearch Loaded: loaded (/usr/lib/systemd/system/elasticsearch.service; enabled; vendor preset: enabled) Active: failed (Result: exit-code) since Thu 2020-09-03 19:50:52 PKT; 2min 18s ago Docs: https://www.elastic.co Process: 948 ExecStart=/usr/share/elasticsearch/bin/systemd-entrypoint -p ${PID_DIR}/elasticsearch.pid --quiet (code=exited, status=1/F Main PID: 948 (code=exited, status=1/FAILURE) ستمبر 03 19:50:52 elk-rewtez systemd-entrypoint[948]: Error: Could not create the Java Virtual Machine. ستمبر 03 19:50:52 elk-rewtez systemd-entrypoint[948]: Error: A fatal exception has occurred.

Can you share your elasticsearch log file ? ---

Sure looks like you are failing on illegal flags on the JVM as JVM won't even start in your first log set (so can't see how you can get second log set at all, which is after node running). > Could not create the Java Virtual Machine. > JvmOptionsParser / flagsFinal Seems you messed up the elasticsearch.yml file or touched the JVM options file. ---

I did not change any thing in JVM options file, just changed some setting in elasticsearch.yml ---

Suggest post full elasticsearch.yml file and jvm options file. As snippets. Also look for ERROR in log as @ylasri suggests. ---
