Hi jaddy321,
Start with resaving permalinks at Settings → Permalinks and hit save. That refreshes the rewrite rules, and this kind of issue usually comes back to those not fully applying after the Multisite setup. Then try visiting /wp-admin/network/ URL directly in case the menu link itself is what is failing.
Also, double-check that the .htaccess file matches the Multisite version. That is usually the main reason the network admin page shows as not found. It is important to confirm whether this is set up as subdomains or subdirectories, and that the config matches that. If those do not line up, it can cause routing issues like this. Clear any network or CDN-level caches as well.

Most of the time it ends up being rewrite rules or config slightly off.

Hey,
This usually happens when the system can’t detect or connect to a configured network administrator or domain. A few things you can check:
- Make sure your device is properly connected to the network
- Verify if you’re logged in with the correct admin or domain account
- Check network settings (DNS / IP configuration)
- Try restarting your router or switching networks
- If it’s a managed system (office/school), the admin permissions might be restricted
If the issue is on a local setup, resetting network settings or reconnecting to the network often fixes it.
