Retry 0: cURL error 52: Empty reply from server

[ostasevych]

Hi! I am using dockerised ES 8.8.2 at my Ubuntu 22.04 Apache server with php 8.2 installed and self-signed certificate.
Yesterday I found in my logs tons of errors:

[fulltextsearch_elasticsearch] Error: Retry 0: cURL error 52: Empty reply from server (see https://curl.haxx.se/libcurl/c/libcurl-errors.html) for http://elastic:password@localhost:9200/mysearch/_doc/files%3A96715?pipeline=attachment

What does it mean and how to improve it?

same error here in indexing. Following.

The same errors appear in my Nextcloud log.

Nextcloud AIO v8.2.1
Full text search - Elasticsearch Platform v28.0.1

If I can help with further log files or something else, feel free to ask for them.

Regards,
simon

Having the same issue. It occurred, after a user uploaded a lot of files, so maybe there is a file there that causes the crash? Having issues identifying the cause. I tried resetting the index, but the error is the same. When manually indexing I get this error:

In ElasticSearchPlatform.php line 202:

                                                              

  [OCA\FullTextSearch\Exceptions\PlatformTemporaryException]  

                                                              

fulltextsearch:index [--output [OUTPUT]] [-r|--no-readline] [--] [<options>]

Fulltextsearch failed. Could not index.
