DevHub · Troubleshooting
Agents cannot reach DevHub after I signed out, or the MCP server is off
Symptom
The MCP server shows Stopped, or an agent gets “sign in required” on every request.
Cause
The MCP server runs only while someone is signed in. Every end of a session stops it: signing out, a session that Vartari ID refuses or withdraws, the end of the 7 days, and offline access running out. DevHub does not start MCP at launch before you sign in, even when “Start MCP with the application” is on. Connections an agent keeps open are closed, and the agent runs and plan steps it held are lost, which the sign-out confirmation warns about.
Solution
Sign in to DevHub. After the sign-in, MCP starts again if it was running when the session ended, or if “Start MCP with the application” is on. If it does not, click Start MCP on the Dashboard. A network that is away for a while does not stop MCP.
