I ran the latest update. The update page 1st prompted me to update the Docker plugin. After doing so i got the message saying i’d need to rebuild the apps in the server as there was an issue with the site image, which seems to happen every 3 or 4 times i update.
In the server when trying to rebuild i get this error message:
x86_64 arch detected.
starting up existing container
+ /usr/bin/docker start app
Error response from daemon: driver failed programming external connectivity on endpoint app (83f3d2e718d3bedaac581e14f9ce21eed1c41564483523b3a7ae2a2af1baf6fe): Error starting userland proxy: listen tcp4 0.0.0.0:443: bind: address already in use
Error: failed to start containers: app
If i try discourse-doctor i get a similar message:

Error response from daemon: driver failed programming external connectivity on endpoint app (8937ea42fba161e42f9ffde7b2958bdba6212f0030aaebbebfe15a1fe69a0156): Error starting userland proxy: listen tcp4 0.0.0.0:443: bind: address already in use

Could you share your app.yml (redact any passwords & sensitive info)
In the meantime, try
sudo systemctl stop nginx
Then try rebuilding?
From what I can see, You somehow have an external nginx running on this server. Unless you’ve configured it to reverse proxy discourse, this is the cause of your failed rebuild.
