Forums are down since rebuild failed during the upgrade (var/discourse/launcher rebuild app).

I tried the solution from [here](https://github.com/moby/moby/issues/25981). The Following solution did not work.

systemctl stop docker  
rm -rf /var/lib/docker/network/files  
systemctl start docker

```plaintext
/usr/bin/docker: Error response from daemon: driver failed programming external connectivity on endpoint app (db53): **Bind for 0.0.0.0:443 failed: port is already allocated**.

# netstat -tulpen | grep 443
tcp6 0 0 :::443 :::* LISTEN 0 488127 30700/docker-proxy  

# docker ps

1d8b7461b27d local_discourse/import "/sbin/boot" 6 weeks ago Up 9 minutes 0.0.0.0:80->80/tcp, 0.0.0.0:443->443/tcp import

```

What else can I do to get the forums back online?

Thanks in advance.

[Solution]

1. Update the Docker Container
2. Stop the Container
3. Run rebuild

I missed step 1 and 2. Because the instructions on the UI said to only to run step 3 using the console.

1. To update the Docker Container

```plaintext
apt-get update
apt-get dist-upgrade lxc-docker

```

1. Stop the Docker Container

```plaintext
docker container ps
docker stop containerID

```

1. Manual Upgrade of Docker Container

```plaintext
cd /var/discourse/
git pull
./launcher rebuild app

```

You may have to run the launcher twice.

Reason for Error “bind was already in use”\>\> Trying to upgrade the discourse while container is running.

I hope this helps someone.
