The bridge is being set up. I used ECS Fargate, used the public.ecr.aws/basemachina/bridge image, and started. The settings for “installing a bridge within the company's network” were completed, and the “connection check from the bridge” was confirmed, but the action of retrieving data from the DB does not work well. If you look at the ECS log, it is displayed as shown below. {“severity”: “Error”, “time”: “2025-0109T 03:59:54.971 653504Z”, “logger”: “bridge.proxy.tcp”, “caller”: “proxy/cp_proxy.go:65", “message”: “unexpected error”, “version”: “1.0.17", “error”: “failed to dial to host\ “169.254.169. 254:53\ “:dial TCP 169.254.169. 254:53: connect: invalid argument"} When I looked up the problem, the following article seems to be related, but I don't know the solution, and I would like your support. https://dev.classmethod.jp/articles/tsnote-ecs-fargate-169-254-169-254/
