Unable to log in to Plesk Obsidian:
PLESK_ERROR: Error: Access for administrator from address ‘127.0.0.1’ is restricted in accordance with IP Access restriction policy currently applied.
This is a Plesk bug with ID PPPM-12569, has already been fixed in Plesk Obsidian 18.0.32, which will become available the next week.
As a temporary workaround, please use one of these solutions:
Use the URL with port 8443 when logging in to Plesk (https://example.com:8443).
Add the following code to the file /usr/local/psa/admin/conf/panel.ini:
realIpFrom = 127.0.0.1
Note: Don’t forget to remove the code once Plesk is updated to Obsidian 18.0.32.
