I created ELK Stack Server with Ubuntu 18.04 LTS and a Linux client with filebeat. Everything works fine together. I tried to install winlogbeat on my Windows PCs. But I can't get it working together. The error log from winlogbeat shows the following messages. I would really appreciate if someone comes forward to help me.
The german error message means s.th. like "No connection possible because destination computer denies connection"
2020-03-09T14:50:25.017+0100 ERROR elasticsearch/elasticsearch.go:261 Error connecting to Elasticsearch at http://192.168.189.110:9200: Get http://192.168.189.110:9200: dial tcp 192.168.189.110:9200: connectex: Es konnte keine Verbindung hergestellt werden, da der Zielcomputer die Verbindung verweigerte.

Edit: I missed that you had both filebeat and winlogbeat in the post. The winlogbeat problem could be firewall, but you will have to test with a windows tool from the failing windows hosts. Some here use "telnet host port" from windows, but I don't do windows
we could solve this issue but now have another one:
We are trying to send the data from winlogbeat to logstash on our elk server. From another linux server filebeat is working. We suppose it is an issue with the certificates but cannot get it working.
Any help is appreciated.

Look here, but it's not very clear how it works with modules, You must have an "output.logstash hosts" somewhere in winlogbeat, try adding these ssl options in the same area.
Look at winlogbeat.reference.yml, it should have all possible options for all sections. Adding any SSL option will enable the output to attempt SSL connections.
