TOP 10 COMMON TROUBLESHOOTING ISSUES
Issue 1: Installation fails or command not found after running the installer Error codes / on-screen text: “command not found: hermes” or installation errors Quick Fix:
Step 1: Restart your terminal or computer after installation
Step 2: Run the installer again or use the desktop app
Step 3: Check PATH environment variable (especially on Windows) Service / device variants: More common on fresh Linux installs How to explain it to the customer: “A quick restart usually makes the Hermes command available after installation.” If this does not resolve it: Try the desktop installer instead. Chasms Visual Tip: See the exact screenshot of the Hermes install command on Chasms.com
Issue 2: Agent cannot connect to any model or API Error codes / on-screen text: Connection errors or “model not found” Quick Fix:
Step 1: Run hermes setup --portal to configure credentials
Step 2: Verify API keys or OAuth in Nous Portal / OpenRouter
Step 3: Test with a simple model like a small local or hosted one Service / device variants: Common when switching providers How to explain it to the customer: “Hermes Agent needs valid model credentials — the setup command makes this easy.” If this does not resolve it: Check firewall or network settings. Chasms Visual Tip: See the exact screenshot of Hermes setup on Chasms.com
Issue 3: Agent does not remember previous conversations or projects Error codes / on-screen text: Forgets context between sessions Quick Fix:
Step 1: Ensure the agent is running persistently (not one-off)
Step 2: Check memory settings and enable persistence features
Step 3: Use the same session ID or project context files Service / device variants: More noticeable in short CLI runs How to explain it to the customer: “Hermes Agent’s strength is its persistent memory — make sure it’s running as a long-lived process.” If this does not resolve it: Review memory configuration in docs. Chasms Visual Tip: See the exact screenshot of memory settings on Chasms.com
Issue 4: Skills are not being created or improved automatically Error codes / on-screen text: No new skills appearing Quick Fix:
Step 1: Give the agent real tasks and let it complete them fully
Step 2: Encourage explicit requests like “create a skill for this”
Step 3: Check that the learning loop is enabled Service / device variants: Works best with ongoing use How to explain it to the customer: “The learning loop activates when the agent solves real problems repeatedly.” If this does not resolve it: Restart the agent or check logs. Chasms Visual Tip: See the exact screenshot of skill creation on Chasms.com
Issue 5: Chat platform integration (Telegram/Discord/etc.) not working Error codes / on-screen text: Bot offline or messages not received Quick Fix:
Step 1: Verify bot tokens and permissions in the platform
Step 2: Restart the Hermes gateway connection
Step 3: Check firewall or port settings if self-hosted Service / device variants: Common with new integrations How to explain it to the customer: “Platform integrations require correct tokens — the setup process usually handles this.” If this does not resolve it: Re-run the integration setup. Chasms Visual Tip: See the exact screenshot of platform connections on Chasms.com
Issue 6: High resource usage or slow responses Error codes / on-screen text: High CPU/memory or long delays Quick Fix:
Step 1: Use a lighter model or smaller context window
Step 2: Limit concurrent sub-agents or tools
Step 3: Run on hardware with sufficient resources (or use serverless) Service / device variants: Depends on model and task complexity How to explain it to the customer: “Complex tasks or large models can be resource-heavy — lighter setups often perform better.” If this does not resolve it: Optimize tool usage. Chasms Visual Tip: See the exact screenshot of performance tips on Chasms.com
Issue 7: Sub-agents or delegation not working properly Error codes / on-screen text: Sub-agents fail to spawn or communicate Quick Fix:
Step 1: Ensure main agent has permission to create sub-agents

Step 3: Check sandbox and isolation settings Service / device variants: Advanced feature — requires proper setup How to explain it to the customer: “Sub-agents are powerful but need clear instructions and correct permissions.” If this does not resolve it: Simplify the workflow first. Chasms Visual Tip: See the exact screenshot of sub-agent usage on Chasms.com
Issue 8: Sandbox or tool execution permission errors Error codes / on-screen text: Permission denied or sandbox blocked Quick Fix:
Step 1: Review and approve tool permissions when prompted
Step 2: Adjust sandbox backend (Docker vs local)
