On other serve 10.128.241.101 it's OK.

I compare version zbxpcp.so they are diffrent.

10.128.241.160:

# sudo dnf list installed | grep zabb
pcp-export-pcp2zabbix.x86_64 5.0.2-5.el8 @AppStream
pcp-export-zabbix-agent.x86_64 5.0.2-5.el8 @AppStream
zabbix-agent.x86_64 5.0.1-1.el8 @zabbix
zabbix-release.noarch 5.0-1.el8 @System

10.128.241.101:

# sudo dnf list installed | grep zabb
pcp-export-pcp2zabbix.x86_64 4.3.2-2.el8 @AppStream
pcp-export-zabbix-agent.x86_64 4.3.2-2.el8 @AppStream
zabbix-agent.x86_64 5.0.1-1.el8 @zabbix
zabbix-release.noarch 5.0-1.el8 @System

On 160 I did dnf update but on 101 no.

I fear that if I update 101 it will also stop working.
But now I need to run the agent on 160. How do I do this?

The installation zabbix agent was the same:

sudo rpm -Uvh https://repo.zabbix.com/zabbix/5.0/rhel/8/x86_64/zabbix-release-5.0-1.el8.noarch.rpm
sudo dnf clean all
sudo dnf -y install zabbix-agent
sudo dnf list installed | grep ^zabbix
sudo sed -i.bak -e "s/Server=127.0.0.1/Server=127.0.0.1,10.128.241.0\/24/g" /etc/zabbix/zabbix_agentd.conf
sudo sed -i.bak -e "s/ServerActive=127.0.0.1/ServerActive=10.128.241.222/g" /etc/zabbix/zabbix_agentd.conf
sudo sed -i.bak -e "s/Hostname=Zabbix server/Hostname=$HOSTNAME/g" /etc/zabbix/zabbix_agentd.conf
cat /etc/zabbix/zabbix_agentd.conf | grep ^Server=
cat /etc/zabbix/zabbix_agentd.conf | grep ^ServerActive=
cat /etc/zabbix/zabbix_agentd.conf | grep ^Hostname=
sudo systemctl enable --now zabbix-agent
sudo systemctl restart zabbix-agent
sudo ps -Fu zabbix
sudo firewall-cmd --add-service=zabbix-agent --permanent
sudo firewall-cmd --reload
sudo firewall-cmd --zone=public --list-all
sudo firewall-cmd --zone=public --list-all | grep zabbix-agent
