Elasticsearch – What blocks the external connection?

[im-fabian]

Hi,
I am trying to set up elastic search on the cloudron Server, because I need it for the nextcloud fulltextsearch. I don't have the knowledge to package it and if I see the forum posts right there have been some discussions about it but it never progressed.

My problem is, that it seems that something within Cloudron blocks external traffic going to elastic search and I can't figure out what. If I run that config on a standalone server it works just fine, on the cloudron server no external connection is possible. I also tried adding a iptables rule without success.

According to netstat elasticsearch is listening:

tcp6       0      0 :::9200                 :::*                    LISTEN      2867282/java

Any ideas who's the interceptor?

Thank you in advance!
Fabian

Have you tried https://docs.cloudron.io/networking/#whitelist-ports already?

Also here the warning that it is a bad idea to install anything on the side of Cloudron on the same server, it will eventually cause update issues and we can't support those edge cases. If it works on another machine anyways already, I strongly advise to use that setup instead until Cloudron may have elasticsearch added.

@nebulon that solves the problem. Thx.

I totally get the warning, however: due to budget restraints I have to do it that way.
