I am receiving error in logstash after upgraded from 7.11.x to 7.16.1  
this log is not frequent, I feel some action is generating that log but I am not sure which action is generating this error, My pipelines are properly configured.  
my logstash server does not has internet connection.  
Please take a look at logstash error screen shot attached here.  
let me know what can be responsible to generate this error.
