Logstash errors

Hi!

Since last week Im having a lot of errors in logstash like these:

[ERROR] 2021-02-03 11:59:46.340 [nioEventLoopGroup-2-1] tcp - Error in Netty pipeline: java.io.IOException: Connection reset by peer

I didn´t make changes in my logstash conf file. Any ideas? I´m running 7.9.3 version on docker.

Regards!
