<!-- Answer --> The 502 Bad Gateway error after upgrading to v1.0.3-beta7 and nginx 1.29 likely means the backend service is unreachable or misconfigured. There are no documented upgrade or migration steps for nginx or DevLake that specifically address this issue, but recent changes may impact backend availability. A recent pull request upgraded nginx in the config-ui Dockerfile to 1.29 for security reasons, but did not change nginx configuration itself [PR #8481](https://github.com/apache/incubator-devlake/pull/8481). Another change disabled CORS middleware in the backend API server, which could affect how nginx proxies requests to the backend and may cause errors if the frontend expects CORS headers [PR #8549](https://github.com/apache/incubator-devlake/pull/8549). There is also a known backend crash after upgrading to v1.0.3-beta7 due to a database migration issue (NULL to int conversion in the 'priority' column), which can prevent the backend from starting and result in 502 errors [PR #8622](https://github.com/apache/incubator-devlake/pull/8622). Troubleshooting steps: - Check that the backend service is running and healthy (not crashing due to migration errors). - Review backend logs for database migration errors or startup failures. - Make sure nginx is correctly proxying requests to the backend service and the backend port is reachable. - If you see migration errors, you may need to manually resolve database issues or confirm migrations are complete. - If you rely on CORS for frontend-backend communication, consider re-enabling CORS middleware or adjusting nginx proxy headers. If you need more targeted help, sharing backend logs or nginx config could help pinpoint the issue. <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot).* --- <sup>How did I do?
