Maybe you are using nginx in "Proxy mode" (Checkbox in Apache&Nginx settings of your app's domain)? If you don't need Apache turn Proxy mode off and restart nginx.
I'm also having this issue
unfortunately this doesn't help much: https://support.plesk.com/hc/en-us/articles/213933865-Nginx-on-Plesk-server-fails-to-start-99-Cannot-assign-requested-address
I fixed it for `<username>` with these commands:
```
# su - <username>
$ /opt/plesk/php/8.0/bin/php /usr/lib64/plesk-9.0/composer.phar global config --no-plugins allow-plugins.plesk/composer-command-info true
```
Since the latest Plesk Obsidian update of the nodejs extension to 2.1.0 we encounter an error when trying to access the configuration. Anyone else noticed this?
