• Debian 11 is approaching its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.80 will be the last release to support it.
    If you are running Plesk Obsidian on Debian 11, we recommend you upgrade those servers to Debian 12 using our dist-upgrade tool.
  • We plan to deprecate and remove the support for XML RPC protocol versions earlier than 1.6.9.1 in Plesk Obsidian 18.0.82. We strongly recommend that you update all existing integrations using earlier versions of the XML RPC protocol to comply with the version 1.6.9.1 specification.

New Pleskian
Hi there,
I'm new to Plesk and I've noticed for the last few days all of my websites have stopped working and I've had to restart the server in AWS. I'm running an AWS instance on Lightsail which is the Plesk Hosting Stack on Ubuntu. In the Plesk logs I've got the following screenshot. Is there a way to fix this?

Thanks in advance for any help. Cheers.
 
Do you know how to log in on the command line of your Plesk server? If so, please execute this command as the root user and show the results:
Code:
# service plesk-ext-monitoring-hcd start
 
I would say the most straightforward way is using the "SSH Terminal" extension in your Plesk panel (to paste in the command prompt use ctrl/cmd+shift+v). You can also use an SSH client installed on your local computer. Please check the following article, which covers all methods.
