Session Expired Error in JetBrains IDE Services Demo

Problem

When starting JetBrains IDE Services Demo after updating docker-compose.yml to the latest version (2026.0.1.366), a "Session expired" error is displayed, and users cannot access the license activation screen.

Cause

The mock-auth section in the docker-compose.yml file does not have the same image tag (version) as the tbe-server section. This version mismatch causes the session issue.

Resolution

To resolve the "Session expired" issue, update the mock-auth section in the docker-compose.yml file to ensure its version matches the one used for tbe-server. For example, use image: registry.jetbrains.team/p/toolbox-enterprise/public/tbe-mock-auth:2026.0.1.366 if the tbe-server version is 2026.0.1.366.

After updating the file, perform the following steps:

1. Run docker compose down to stop all running containers.
2. Run docker compose up to restart everything cleanly.

Once these changes are made, the "Session expired" message should no longer appear, and the license activation screen should be accessible.
