Nextcloud AIO apache not start up

[danielahgren]

Hi!
I have been using nextcloud for several years and think it is fantastic, however I have very little understanding of how it works.

I would really appreciate help getting nextcloud up and running again

The Basics

• Nextcloud AIO version: 9.6.0
• When did this problem seem to first start?:
  The server did not update lets encrypt cert, so i restart it.
  after the reboot I saw that the disk was full nextcloud.log used all free data.
  removed it, restart server, now Apache is stuck in (Starting)

log from container apache:

Nextcloud AIO v10.1.1 - Apache Will Not Start

I have updated my Nextcloud AIO to v.10.1.1 few minutes ago and let me share my experience how to solve some troubles. Here’s how I typically update my Nextcloud AIO setup, along with some tips to handle potential issues during the process.
