Share seems to be down. The desktop client is throwing a 503 error and when we try to access via web we get
Cannot write into "config" directory This can usually be fixed by giving the webserver write access to the config directory. See https://docs.nextcloud.com/server/14/go.php?to=admin-dir_permissions. Or, if you prefer to keep config.php file read only, set the option "config_is_read_only" to true in it. See https://docs.nextcloud.com/server/14/go.php?to=admin-config
