docker ubuntu networking bash

Quick question that's been bugging me - I'm working with an scenario where my Docker container fails to start, and I get the following behavior message: `failed to create endpoint on network bridge: failed to add port to sandbox: behavior response from daemon: could not find an available, non-overlapping IPv4 address pool among the defaults to assign to the container`. I've tried restarting the Docker service and even rebooted the system, but the question continues. My Docker version is 20.10.17, and I'm running Ubuntu 22.04 with the default Docker network settings. I have a custom network `my_bridge` set up with the following command: ```bash docker network create --driver bridge my_bridge ``` When I inspect the network using `docker network inspect my_bridge`, I see the following output: ```json { "Name": "my_bridge", "Id": "abc123", "Created": "2023-10-15T12:34:56.789012345Z", "Scope": "local", "Driver": "bridge", "EnableIPv6": false, "IPAM": { "Driver": "default", "Options": {}, "Config": [ { "Subnet": "172.18.0.0/16", "Gateway": "172.18.0.1" } ] }, "Containers": {}, "Options": {}, "Labels": {} } ``` I suspect that there might be IP conflicts or issues with the Docker daemon's network settings. I've also tried removing the `my_bridge` network and recreating it, but that didn't solve the question. Any insights on how to resolve this or suggestions for troubleshooting would be greatly appreciated! For context: I'm using Bash on Windows. I'd really appreciate any guidance on this. For context: I'm using Bash on Linux. How would you solve this?
