Hi,
it looks like something went wrong during the update and the Apache container didn’t start properly. I’ve had similar issues in the past, so I created a simple and reliable update routine that has consistently worked 100% for me.
I always verify the result using Portainer, where I can clearly see that all the Nextcloud AIO containers have started successfully after the update.
I shared my routine here:

Feel free to check it out — it might help you get AIO back up and running or at least avoid similar issues in the future.
If you have any questions, I’m happy to help.
