I have PHP web app which interacts with Elasticsearch. It worked well but recently i got error with next text:

```auto
2022-01-13 16:43:59 [95.161.173.18][4669][1tjhk618ubj7tjniq1utjpbntj][error][application] delete elastic

...

```

Meanwhile i see next in /var/log/Elasticsearch/elasticsearch\_index\_indexing\_slowlog.log:

```auto
[2022-01-13T16:43:59,936][WARN][index.indexing.slowlog.index] [5R0q8j_] [new_rid_elastic/0xTeeKV4T3myNSjWiL0oxQ] took[1.2ms], took_millis[1], type[rid-elastic], id[NXSuU34B855L8Ty5UGi_], routing[], source[{}]
[2022-01-13T16:44:01,542][WARN][index.indexing.slowlog.index] [5R0q8j_] [new_rid_elastic/0xTeeKV4T3myNSjWiL0oxQ] took[2.2ms], took_millis[2], type[rid-elastic], id[540757], routing[], source[{}]
...

```

So what's going on? How to fix that time out related error and why it have occurred now?

HI @zeleniy !  
Have you checked if there is any security policy applied to the server? Maybe active iptables rules?  
Did you try to make a request via cURL?  
If the connection to your server has SSL/TLS, it is interesting to see the request form if it is compatible with these protocols.
