Hello, @Haugli92 . Our team is currently investigating the report of the false-positive alerts. You can follow the status of the report here:

Hello @Sebahat.hadzhi , We are also experiencing issues with the Monitoring feature in Plesk. Whenever we try to open it, we receive the following error message:

“An unexpected error occurred.”

This problem has been happening since today (5 August 2025).

Is this issue already known to you?

 

[Sebahat.hadzhi]

@Petje , yes, you were likely seeing the error due to the reported issue, which is sorted out now. Please let us know if it is still ongoing on your end.

We're having kinda the same problem. After some time the screen goes white with "An unexpected error occured".
In the Plesk log we have multiple entries:
extension/monitoring -> /opt/psa/admin/plib/modules/monitoring/library/Http/HttpClient.php(122): Read timed out after 20 seconds
