Introduction
VPN users often run into connection errors that seem confusing at first glance. One common phrase people search is “Ivati VPN Client 1111 Host Not Found.” Whether you’re trying to connect through a corporate VPN, using third-party software, or troubleshooting a network blockage, this term reflects a common connection failure: the VPN client can’t locate or reach the host server.
Although there is no widely recognized product officially named “Ivati VPN Client,” the phrase is frequently used by users referring to Ivanti VPN, custom corporate VPN clients, or miswritten variations like Ivati / Ivanti / Ivaty / Ivatl VPN client. Combined with the error “1111 host not found,” it typically points to a DNS issue, misconfiguration, server unavailability, or client-side networking problem.
In this detailed 3000-word guide, we’ll break down everything related to this phrase: causes, solutions, VPN setup steps, potential software behind it, FAQs, security insights, and best practices. The goal is to cover every angle so users searching for “Ivati VPN Client 1111 Host Not Found” find answers in one place.
What Does “Ivati VPN Client 1111 Host Not Found” Refer To?
There are two major components in this phrase:
- Ivati VPN Client
- Likely a misspelling or alternate name for Ivanti Secure VPN, a commonly deployed enterprise VPN solution.
- Some users also refer to private VPN clients created for workplaces, schools, and government networks as “Ivati” because of internal branding.
- Others misinterpret it as a VPN type, similar to OpenVPN, WireGuard, or Cisco AnyConnect.
- 1111 Host Not Found
- “1111” is not a universal error code, but could resemble:
- DNS 1.1.1.1 configurations (Cloudflare DNS)
- Host ID numbers or internal port references
- A shorthand for connection timed out or unreachable host
- “Host Not Found” is a generic DNS resolution error, meaning the VPN client can’t locate its server hostname (e.g., vpn.company.com or custom domain).
- “1111” is not a universal error code, but could resemble:
When combined, “Ivati VPN Client 1111 Host Not Found” usually appears when someone attempts to connect to a VPN server but the hostname can’t be resolved or reached.
Common Causes Behind the Error
If you’re searching this phrase or seeing a similar error message, one or more of the following issues may apply:
✅ 1. DNS Failure
The VPN client can’t translate the server’s hostname into an IP address.
- Wrong DNS settings
- ISP DNS block
- Cloudflare 1.1.1.1 misconfiguration
- Firewall blocking DNS requests
✅ 2. Wrong Server Address
The hostname you typed might be:
- Misspelled
- Outdated
- Removed or replaced by admin
- Pointing to an inactive IP
✅ 3. Server Offline
If your organization’s VPN server or third-party VPN node is down, the Ivati (or Ivanti) client won’t connect.
✅ 4. Firewall or Antivirus Blocking
Security software sometimes blocks VPN protocols, especially IPSec, SSL VPN, L2TP, or custom ports.
✅ 5. No Internet Connectivity
Before blaming the VPN, check general connectivity. If basic websites won’t load, the VPN obviously won’t connect either.
✅ 6. Expired VPN Credentials
User accounts with expired passwords often fail with generic host not found or login timeouts.
✅ 7. Network Restrictions
Corporate, hotel, school, or public Wi-Fi networks may block specific VPN ports or DNS resolvers like 1.1.1.1.
✅ 8. Misconfigured Proxy
If your system uses a proxy that conflicts with the VPN’s DNS preferences, the host lookup may fail.
How to Fix “Ivati VPN Client 1111 Host Not Found” – Step-by-Step
Here’s a structured troubleshooting checklist:
✅ Step 1: Test Your Internet
- Open a browser and visit any website.
- If pages don’t load, fix your internet connection first.
✅ Step 2: Check the Server Address
- Re-enter the VPN hostname manually.
- Confirm the correct name with your admin or service provider.
✅ Step 3: Switch DNS Servers
Try using Cloudflare (1.1.1.1 and 1.0.0.1) or Google DNS (8.8.8.8 or 8.8.4.4):
- On Windows: Network Settings → Adapter → IPv4 → Manual DNS
- On Android/iOS: Set Private DNS to dns.cloudflare.com
If you were already using 1.1.1.1, test using ISP default DNS.
✅ Step 4: Flush Local DNS Cache (Windows)
Open Command Prompt (Admin) and run:
ipconfig /flushdns
Then restart your VPN client.
✅ Step 5: Disable Firewall Temporarily
- Turn off Windows Firewall or third-party antivirus for a moment.
- Retry connecting. If it works, add the VPN client to the exception list.
✅ Step 6: Try IP Instead of Hostname
If you know the VPN server’s IP, enter it directly instead of hostname.
✅ Step 7: Reinstall or Update the Client
If you’re using Ivanti Secure Access, OpenVPN, or another branded client:
- Download the latest version from the official source.
- Uninstall old client before reinstalling.
✅ Step 8: Contact Admin or VPN Support
If it’s a business VPN, only the network admin can confirm server status. Problems like certificate expiration, network rerouting, or server migration require backend fixes.
Ivati VPN vs Ivanti VPN – Clearing the Confusion
Many users type Ivati VPN while referring to Ivanti Secure VPN Client. Ivanti is an official enterprise solution used by thousands of organizations globally.
Possible reasons for spelling confusion:
- Typing error
- Regional pronunciation differences
- Misspelled in documentation
- Generic reference to VPN login app
- Lack of branding clarity
So if you see “Ivati VPN client host not found,” it’s likely the Ivanti client or a custom deployment.
What Is Cloudflare 1.1.1.1 and How It Relates?
Some users see “1111 host not found” because of DNS conflicts involving Cloudflare’s 1.1.1.1 DNS. VPN clients rely heavily on DNS for routing traffic. If:
- DNS resolution is blocked,
- IPv6 is misconfigured,
- Or the VPN enforces split tunneling via another DNS,
You can end up with host not found messages.
Alternative Keywords & Related Searches
People also look for variations like:
- Ivati vpn client error 1111

- Cloudflare 1111 vpn issue
- VPN dns host not responding
- Can’t resolve host on vpn client
- VPN server not found
- VPN hostname lookup failed
Using these in your search can pull different but related solutions.
Device-Specific Fixes
✅ Windows (10/11)
- Run Command Prompt as admin
- Use:
netsh winsock reset
ipconfig /flushdns
- Restart and reconnect
✅ macOS
- Go to System Settings → Network
- Turn Wi-Fi off and on
- Use:
sudo dscacheutil -flushcache
sudo killall -HUP mDNSResponder
✅ Android/iOS
- Reset network settings
- Turn Airplane mode on/off
- Change Private DNS to “Automatic”
✅ Linux
- Check
/etc/resolv.conf - Restart VPN service:
sudo systemctl restart NetworkManager
VPN Protocol Conflicts
Some VPN servers use:
- SSL/TLS (HTTPS)
- IPSec
- L2TP
- PPTP
- WireGuard
- OpenVPN
If your Ivati VPN client tries to connect using an unsupported protocol, you’ll see connection failures. A blocked port (e.g., 443, 1194, 500, 4500) further adds to the “host not found” behavior.
Corporate Environments and SSL VPN Gateways
If you’re using a workplace VPN:
- Server name may have changed after migration
- SSL certificates might have expired
- Firewall rules may have updated
- Auth policies may have been removed
Always test using your work network’s official portal or updated hostname.
DNS vs IP-Based VPN Access
Sometimes VPN admins assign both:
- Hostnames like vpn.office.net
- IPs like 203.15.110.51
If DNS is failing, direct IP entry can bypass the host lookup error.
Cloudflare WARP / 1.1.1.1 App Conflicts
If you’re using the Cloudflare WARP VPN app, disable it before connecting to an Ivanti/Ivati VPN because:
- They can conflict over DNS tunneling
- Both may try to route traffic
Switch it off and retry your VPN client.
Advanced Troubleshooting
If the basic fixes don’t solve the issue, try the following:
✅ Check Log Files
Most VPN clients provide logs with more detailed errors. Search terms like:
- dns failure
- cannot resolve host
- tunnel failed
- connection refused
✅ Test DNS with Command Line
nslookup vpn.example.com
ping vpn.example.com
✅ Bypass IPv6
Disable IPv6 in network settings temporarily and retry the VPN.
✅ Change Network
If you’re on office Wi-Fi, try mobile hotspot or home internet.
Role of Certificates and Authentication Servers
Some Ivanti-based VPNs use certificates for secure connection. If:
- Certificate is invalid,
- It’s not trusted by your OS, or
- Revocation checks fail,
The error “host not found” may appear even though the real problem is TLS-level failure.
VPN Gateways and Port Restrictions
Common VPN communication ports include:
- 443 (SSL/TLS)
- 1194 (OpenVPN)
- 500/4500 (IPSec)
If a firewall blocks these, DNS queries may not complete, resulting in host resolution errors.
Reinstalling Ivanti Secure Client (If Applicable)
If you’re actually using Ivanti:
- Uninstall the current client
- Reboot your system
- Download the latest version from your corporate or official source
- Re-enter credentials and domain
Split Tunneling and Routing Problems
Some VPNs use split tunneling, where only corporate traffic goes through the VPN. This sometimes confuses the DNS resolver.
Solution:
- Disable split tunneling temporarily
- Or adjust DNS precedence order
Proxy Servers & Interference
A proxy can block hostname resolution. Disable the proxy or configure your VPN to bypass it.
On Windows:
- Internet Options → Connections → LAN Settings → Uncheck Proxy
Mobile Hotspots and Public Wi-Fi
Many public hotspots block VPN protocols. If this is when you’re seeing “Ivati VPN client 1111 host not found,” switch networks.
Enterprise Auto-Config Profiles
If auto-config profiles (.mobileconfig, .ovpn, .xml) are outdated, hostnames stored inside may be invalid. Get updated files from your admin.
Resetting Network Settings
As a last-resort local fix:
Windows:
netsh int ip reset
netsh advfirewall reset
Android:
Settings → System → Reset Options → Reset Wi-Fi, Mobile & Bluetooth
iPhone:
Settings → General → Reset → Reset Network Settings
Security Considerations
Never connect to unknown or unverified VPN servers, especially if the error appears while using a cracked or unofficial client. Malicious VPNs may misroute DNS or use deceptive hostnames.
