Remote Access Issues: Remote Access is not properly enabled.
DNS Rebinding: Your router or DNS provider is preventing DNS Rebinding.

3.1 Subnet Mismatch

What is a subnet, and why does it matter for Plex?

A subnet is a logical subdivision of an IP network. Devices on the same subnet can communicate directly with each other. If your Plex server and app are on different subnets, they may not be able to find each other.

How to Check Subnet:

Windows:
- Open Command Prompt (search for “cmd”).
- Type ipconfig and press Enter.
- Look for the “IPv4 Address” and “Subnet Mask” for both your server and the device running the Plex app.
macOS:
- Open Terminal (Applications > Utilities).
- Type ifconfig and press Enter.
- Look for the “inet” (IPv4 Address) and “netmask” for both your server and the device running the Plex app.

Example:

Server:
- IPv4 Address: 192.168.1.10
- Subnet Mask: 255.255.255.0
App:
- IPv4 Address: 192.168.1.20
- Subnet Mask: 255.255.255.0

In this example, both devices are on the same subnet because the first three octets of their IP addresses (192.168.1) are the same, and the subnet mask is 255.255.255.0.

How to Resolve Subnet Mismatch:

Ensure that both the server and the app are connected to the same router.
Check your router’s configuration to ensure that it’s not creating multiple subnets unintentionally.

3.2 Remote Access Issues

Why can’t I access my Plex server remotely?

Remote Access allows you to access your Plex library from outside your home network. If Remote Access is not properly enabled, you won’t be able to stream media when you’re away from home.

How to Enable Remote Access:

Open Plex Media Server settings.
Go to Settings > Remote Access.
Click the “Enable Remote Access” button.
Plex will attempt to automatically configure your router. If it’s successful, you’ll see a message saying “Fully accessible outside your network.”
If automatic configuration fails, you may need to manually configure port forwarding on your router.

Manual Port Forwarding:

Find your Plex Media Server’s private IP address (see Subnet Mismatch section above).
Log in to your router’s web interface.
Find the “Port Forwarding” or “NAT Forwarding” section.
Create a new port forwarding rule with the following settings:
- Service Name: Plex Media Server
- Protocol: TCP
- External Port: 32400
- Internal Port: 32400
- Internal IP Address: Your Plex Media Server’s private IP address
Save the port forwarding rule and restart your router.

According to research from the Uptime Institute, in July 2025, over 70% of internet traffic will be video content. Properly configured remote access ensures a seamless streaming experience, regardless of your location.

3.3 DNS Rebinding

What is DNS Rebinding, and how does it affect Plex?

DNS Rebinding is a security mechanism that prevents websites from accessing resources on your local network. Some routers and DNS providers block DNS Rebinding by default, which can prevent Plex apps from connecting to your server on the local network.

How to Check for DNS Rebinding Issues:

Try accessing your Plex server using its local IP address (e.g., http://192.168.1.10:32400/web) instead of its hostname (e.g., http://your-server-name.local:32400/web). If this works, it’s likely a DNS Rebinding issue.
Check your router’s settings for any options related to DNS Rebinding or DNS security.

How to Resolve DNS Rebinding Issues:

Router Configuration:
- Log in to your router’s web interface.
- Look for settings related to DNS Rebinding or DNS security.
- Disable any settings that are blocking DNS Rebinding.
- Add an exception for your Plex server’s hostname.
Custom DNS Server:
- Use a custom DNS server that allows DNS Rebinding, such as Google Public DNS (8.8.8.8 and 8.8.4.4) or Cloudflare DNS (1.1.1.1).
- Configure your router to use the custom DNS server.
