- Plesk and websites are unavailable
- SSH to the server is possible
- All ports are filtered, except the port 22 (SSH)
- The package
iptables-serviceshas been installed just recently
The extension (D)DoS Deflate Interface was updated from version 4.1.0 to 4.1.2. During this update, the package iptables-services was installed and all the firewall rules were reset.
The issue will be fixed in the next extension release.
Currently, the following workaround might be applied:
Connect to the server via SSH
Install the Plesk Firewall:
# plesk installer --select-release-current --install-component psa-firewall
Enable the firewall:
# /usr/local/psa/bin/modules/firewall/settings -e
All the necessary rules will be applied automatically.
