Investigating

After updating ea-nginx to version ea-nginx-1.26.3-4.el*.cloudlinux.1.1, servers with Imunify360 installed may experience Nginx service going down due to this or a similar error:

---->>
nginx: [emerg] bind() to 0.0.0.0:52228 failed (98: Address already in use)
-----^^

Our developers are preparing a hotfix, which should be available today.

Until the hotfix is ready, we suggest using the previous version ea-nginx-1.26.3-4.el*.cloudlinux.1 with the workaround.
Here are the steps for the workaround:
-----------------------------
yum downgrade ea-nginx
mkdir -p /etc/sysconfig/imunify360
touch /etc/sysconfig/imunify360/imunify360-merged.config
/scripts/ea-nginx config --all
-----------------------------
