Starting Elasticsearch fails

Hi, I had an outage at my Server (self-hosted) and now every time I want to start ES this error appears:

Jul 10 08:15:44 pelk logstash[720]: [2021-07-10T08:15:44,162][WARN ][logstash.outputs.elasticsearch][pfelk] Attempted to resurrect connection to dead ES instance, but got an error. {:url=>"http://elastic:xxxxxx@", :error_type=>LogStash::Outputs::ElasticSearch::HttpClient::Pool::HostUnreachableError, :error=>"Elasticsearch Unreachable: [http://elastic:xxxxxx@][Manticore::SocketException] Connection refused (Connection refused)"}

I can't reach the given IP:Port in the browser either.
How can I make it stop trying to resurrect that connection and just make a new one?
Is there some kind of hard reset for ES?
I obviously tried a reboot but it didn't help.
Kibana Logstash etc. are working well and all was fine before the outage (no settings changed etc.)

What is in the Elasticsearch logs? Which version of Elasticsearch are you using?

Ah it works again. I thought the errors I posted were the relevant errors but it turns out I had more detailed ones in the log file which helped me solve the problem.

Thanks anyway for the help. :+1:
