Error 113: Creative Cloud Server Connectivity Reset (2026 Guide)

Adobe Error 113 occurs when the Creative Cloud desktop app or installer loses network synchronization with Adobe authentication servers mid-transmission due to an abrupt connection reset (TCP RST). This connection termination is triggered by real-time network inspection, corrupted local DNS caches, invalid host file redirects, or security protocols rejecting the SSL/TLS handshake. Resolving Error 113 requires flushing the system DNS cache, clearing socket deadlocks, and restoring unblocked network access to Adobe endpoints.

Fast-Fix: The 45-Second Solution

If your internet connection is active elsewhere, Adobe Error 113 indicates a blocked network socket or interrupted handshake during server verification. Immediately open Command Prompt or Terminal as Administrator and run ipconfig /flushdns (or sudo dscacheutil -flushcache on macOS), then disable active VPNs and third-party firewalls. Ensure your operating system supports current TLS 1.2/1.3 security protocols before relaunching the installer.

Quick Status Snapshot

• Severity Tier: Moderate
• Project Risk: Low (App installation and licensing validation are blocked; local project files and assets remain safe)
• Root Cause: Unexpected TCP RST packet sent during session handshake between Creative Cloud Desktop Service and Adobe CDN endpoints.
• Rare Cause: Outdated operating system root certificates refusing current TLS 1.3 security standards.

Low-Friction vs. High-Friction Scenarios

• If it happens during initial app download (0–20% progress): A local DNS server or corporate proxy is dropping packets sent to Adobe asset distribution networks.
• If it happens during license activation or background sync: An active VPN, web filtering tool, or invalid loopback entry in the system hosts file is severing an established SSL socket.

Service-Level Mechanism

The Adobe Desktop Service (AGSService) maintains persistent background sockets using secure web protocols to communicate with Adobe authentication endpoints (such as cc-api-data.adobe.io). Error 113 is raised when an intermediate network hop or local filter sends a TCP RST packet to abruptly close the port. Think of it like a municipal water line where a safety valve slams shut mid-flow because it detected an unexpected pressure spike—the connection doesn’t just trickle out, it is instantly terminated to prevent unauthorized access.

Escalation Variables

• Enterprise Network Policies: Deep Packet Inspection (DPI) firewalls on corporate or campus networks blocking non-standard TLS session handshakes.
• Legacy OS Build Numbers: Outdated Windows or macOS installations lacking updated root certificate authority (CA) bundles required for modern endpoint validation.
• VPN Interruption: Network routing changes during active VPN reconnect cycles dropping persistent WebSocket connections.

The Cost of Delay: Immediate → Next Session

Ignoring Error 113 halts software installations and prevents the Creative Cloud Desktop app from validating user entitlements. If left unaddressed, active applications will revert to trial mode or throw licensing errors, preventing access to cloud fonts, libraries, and generative services during subsequent work sessions.

What To Do Right Now

1. Open your terminal application with Administrator privileges.
2. Flush the system DNS cache to clear outdated IP routing tables.
3. Turn off active VPN connections, proxy servers, and third-party web protection tools.
4. Restart the Adobe Desktop Service from your system services manager or restart the machine.

Hard-Stop Failure Signals

• Global SSL Certificate Failures: Web browsers continuously report untrusted security certificate errors across multiple external sites, indicating system-wide clock or root certificate corruption.
• Total Network Interface Loss: Executing network stack resets removes default gateway routes, requiring manual network adapter driver reinstalls.

The Professional Recovery Sequence

Method 1: Flush DNS and Reset Network Sockets

On Windows:

1. Press Win + X and select Terminal (Admin) or Command Prompt (Admin).
2. Type the following commands one by one, pressing Enter after each:DOS ipconfig /flushdns netsh winsock reset netsh int ip reset
3. Restart your computer to apply the updated socket configuration.

On macOS:

1. Open Terminal (Cmd + Space, type Terminal).
2. Execute the DNS flush command:Bash sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder
3. Enter your administrator password when prompted and press Enter.

Method 2: Inspect and Clean System Hosts File

Stale or malicious entries in the operating system hosts file will forcibly re-route Adobe authentication traffic back to your local machine, triggering a reset error.

1. Open your system text editor as Administrator.
   • Windows: Run Notepad as Administrator and open C:\Windows\System32\drivers\etc\hosts.
   • macOS: Open Terminal and run sudo nano /private/etc/hosts.
2. Look for any line containing adobe.com, adobe.io, or lmlicenses.wip4.adobe.com.
3. Comment out those lines by adding # to the beginning of the line, or delete them entirely. For detailed manual steps, see Error P207: How to Flush DNS for Adobe CC Authentication.
4. Save the file and close the editor.

Method 3: Clear Adobe Local Session Caches

Corrupted session state tokens can cause the local desktop service to send invalid handshake keys, triggering a server-side reset.

1. Close all Adobe applications.
2. Navigate to the OOBE cache directory:
   • Windows: %LocalAppData%\Adobe\OOBE
   • macOS: ~/Library/Application Support/Adobe/OOBE
3. Delete the opm.db file inside the OOBE folder.
4. Relaunch the Creative Cloud Desktop application and sign in again.

Method 4: Configure Firewall Exceptions

1. Open your firewall settings menu.
2. Add inbound and outbound allow rules for the following processes:
   • Creative Cloud.exe (or Creative Cloud app on macOS)
   • Adobe Desktop Service.exe
   • AdobeIPCBroker.exe
3. Ensure port 443 (HTTPS) and port 80 (HTTP) allow outbound traffic to .adobe.com and .adobe.io.

Required Resource Allocation

• Bandwidth: Stable internet connection with at least 5 Mbps downstream capacity.
• Privileges: Local Administrator or Root user access to execute socket resets and edit system files.
• Security Protocols: Enabled support for TLS 1.2 or TLS 1.3 in system internet properties.

Final Render

Flushing deadlocked DNS caches and clearing modified host entries directly addresses the underlying cause of Error 113. Once socket pathways are clear and secure handshakes are restored, Creative Cloud applications will download, update, and authenticate without interruption.
