A high number of incoming requests originate from one or more unique IP addresses. This could indicate a bot attack. The following guide shows how to check for and block suspicious IP addresses.

bndiagnostic was not useful. Could you please tell us why?

my other instance is mint and fast

Describe your issue as much as you can

I can't reach my instance's admin endpoint and can't reach my dns name as well, and IP address as well

Hi @rapoposolutions,

Thanks for using Bitnami. According to the bndiagnostic information you shared, your getting around 49k out of the total 51k requests on your server from a couple of IP addresses

-----------------------------------
Check number of lines of Apache access log
-----------------------------------
Running: wc -l access_log
In: /opt/bitnami/apache2/logs/

Output:

50987 access_log

-----------------------------------
Check performance issues: Count number of requests for the 10 most active IP addresses in the last 100.000 requests
-----------------------------------
Running: tail -n 100000 access_log | awk '{print $1}' | sort | uniq -c | sort -nr | head -n 10 | awk '{print $1}'
In: /opt/bitnami/apache2/logs/

Output:

This is causing that your instance can't attend new requests from other clients. We recommend you to check what requests are those IPs performing and optionally blocked them (in case they are bots performing attacks to your server)
