XenForo_Exception: Elasticsearch indexing failed. See the server error log for more details.

What is in the server error log?

What is in the server error log?

you mean the error_log file found in the root of the forums folder or an error log in the actual server /var/log?

the error_log file in root forum folder doesnt contain anything

I already posted the error logs I got from Xenforo

 

[XxUnkn0wnxX]

this is from the /var/log/elasticsearch/Xenportal.log

https://gist.github.com/XxUnkn0wnxX/f07faa5eead0dc84174e46987310a416

had to post in there because Xenforo say to many characters.

reading over long I think it permission / ownership issues and I'm not sure how to fix I already set the /var/elasticsearch folder to chown -R elasticsearch:elasticsearch /var/elasticsearch

and chmod 755 the folder

Any Clues on how to fix?

Edit: Fixed it

had to do

sudo chmod 755 -R /var/elasticsearch
sudo chown elasticsearch:elasticsearch -R /var/elasticsearch

also I changed the index name to lowercase

either it was the sudo before commands or the changing to lowercase that fixed it.
