Desktop sync client will only sync if I manually launch the client

Nextcloud version : 19.0.0
Operating system and version : PopOS 20.04
Apache or nginx version : apache, whichever comes with the nextcloud docker image
PHP version (eg, 7.1): not sure how to check

The issue you are facing:
my nextcloud desktop client will not sync without being manually opened despite having the setting to enable at startup

Is this the first time you’ve seen this error? (Y/N): Y

Steps to replicate it:

  1. cd ~/nextcloud/documents
  2. “touch test.txt”
  3. note that ~/nextcloud/documents/touch.txt exists
  4. open nextcloud webUI
  5. note that “Documents>test.txt” does NOT exist
  6. launch nextcloud desktop app
  7. refresh webUI
  8. note that “Documents>test.txt” DOES exist

The output of your Apache/nginx/system log in /var/log/____:
I’m using nextcloud in docker. So I

docker exec -it nextcloud /bin/bash

When I tried to cat /var/log/apache2/error.log it just hung on the prompt.
