If TeamViewer is stuck on connecting or not working, this guide shows simple steps to fix it. Check your network, permissions, firewall, and more, or try AnyViewer for reliable remote access.
When TeamViewer is stuck on connecting, refuses to log in, or shows the “Unable to connect to partner” message, it can be frustrating and disruptive. Many users encounter issues like TeamViewer not working or TeamViewer not connecting, often due to network instability, firewall restrictions, proxy conflicts, IPv6 interference, licensing limitations, or temporary server outages.
Prefer a smoother experience? AnyViewer, one of the best TeamViewer alternatives, delivers fast, reliable remote access without the usual complications, and it’s free to use, even for commercial purposes.
Whether you are using the free version or a licensed edition of TeamViewer on Windows, macOS, Android, or iOS, these nine solutions can help resolve issues where TeamViewer is not connecting. Each method is practical, cross-platform, and effective in restoring stable remote access.
An unstable network often causes connection issues in TeamViewer. Weak Wi-Fi, VPN interference, or proxy rules can trigger delays, timeouts, or complete failures to connect.
Steps:
Step 1. Press "Win + R", type "cmd", and press "Enter".
Step 2. Enter "ping -t 8.8.8.8" and monitor the results. Frequent latency spikes or packet loss indicate an unstable network.
Step 3. Run a quick Speedtest or restart your router. If possible, switch to a wired connection for a more reliable link.
If your internet connection looks fine but the issue persists, continue to the next method.
Restricted permissions can prevent you from connecting to or taking control of the remote device. Ensuring full access often resolves these problems.
Steps:
Step 1. On the remote device, open "TeamViewer", click the "gear icon", and select "Options".
Step 2. Navigate to "Advanced" and choose "Show advanced options".
Step 3. Under "Advanced settings for connections to this computer", change "Access Control" to "Full Access".
This guarantees complete control over the remote system and eliminates most permission-related connection barriers.
If TeamViewer continues to fail during the connection process, some Windows components may be getting in the way. User Account Control (UAC) can block actions that require elevated privileges, and certain Remote Desktop services may also conflict with remote access tools.
Firewall rules or proxy configurations can stop TeamViewer from accessing the ports it needs to establish a stable connection.
Steps:
Step 1. Go to "Windows Defender Firewall > Allow an app through Firewall".
Step 2. Click "Change settings" and ensure "TeamViewer Remote Control Service" is enabled.
Step 3. Open "Control Panel > Internet Options > Connections > LAN Settings" and disable "Use a proxy server for your LAN" if it’s switched on.
If dealing with network rules is too time-consuming, tools like "AnyViewer" offer instant connectivity without complicated firewall adjustments.
IPv6 conflicts can unexpectedly break TeamViewer’s connection process, resulting in errors like “Cannot connect to partner.”
Steps:
Step 1. Press "Win + R", enter "ncpa.cpl", and press "Enter".
Step 2. Right-click your active network and select "Properties".
Step 3. Clear the checkbox for "Internet Protocol Version 6 (TCP/IPv6)", then click "OK".
Step 4. Perform the same adjustment on the remote machine.
Restart both devices and try again. This simple change often clears hidden connection issues.
Running an outdated build or using a non-official installer can trigger connection and compatibility problems.
Steps:
Step 1. Open "TeamViewer", go to the "Menu (≡)", and select "Check for new version".
Step 2. If the update doesn’t resolve the issue, uninstall TeamViewer through "Control Panel > Programs and Features", then download and reinstall the newest version from the official site.
Mac users can also explore alternatives like "Microsoft Remote Desktop" or even use an "iPad as a secondary display" to improve workflow efficiency.
When TeamViewer fails during login or verification, corrupted network cache or protocol stacks may be to blame.
Steps:
Step 1. Open "Command Prompt" as an Administrator.
Step 2. Run these commands one at a time:
Step 3. Restart your computer and attempt to reconnect through TeamViewer.
Refreshing these settings often clears hidden network conflicts and restores stable communication.
At times, the connection problem has nothing to do with your device or network; TeamViewer’s servers may be experiencing issues.
Steps:
Step 1. Visit the official "TeamViewer server status" page.
Step 2. See whether servers in your region are currently down or under maintenance.
If there’s a temporary outage, you’ll need to wait it out or switch to a more stable option like "AnyViewer" in the meantime.
Security tools, startup programs, or hidden background services can interfere with TeamViewer’s ability to connect and stay connected.
Steps:
Step 1. Press "Win + R", type "msconfig", and press "Enter".
Step 2. Under "General", choose "Selective startup" and uncheck "Load startup items".
Step 3. Go to the "Services" tab, select "Hide all Microsoft services", then click "Disable all".
Step 4. Restart your computer.
Step 5. Temporarily turn off your antivirus and test TeamViewer again.
A clean boot helps identify software conflicts that silently break your remote sessions.
