# The UI is not showing after 'Device successfully unlocked, please wait for second stage.'

Applies to:

nodl One (black, etched logo) with activated disk encryption and nodl Dojo (red, etched logo)

# Symptoms

After entering the unlock password, the browser either goes to a blank page or an error page.

# Cause

The reason could be one of the following:

  • inner nginx didn't start
  • inner php didn't start
  • there is a configuration issue

# Solution

First, ssh into your nodl (opens new window)

Then, check if nginx is running:

The output of the following command should have two nginx master processes running:

top

If not, run:

/etc/init.d/nginx restart

Check if php-fpm is running:

The output of the following command should have two php-fpm master processes running:

top

If not, run:

/etc/init.d/php7.2-fpm restart

Check if configuration is set up properly

grep inner /etc/php/7.2/fpm/pool.d/www.conf

The above command should show:

listen = /run/php/php7.2-fpm-inner.sock

If that is not correct, then something wrong happened during the upgrade. Run the below to manually upgrade the system:

for nodl one:

/usr/share/nodl/update-nodl.sh nodl-one

for nodl dojo:

/usr/share/nodl/update-nodl.sh nodl-dojo

Then restart php-fpm with:

/etc/init.d/php7.2-fpm restart

If the above doesn't fix it, it's worth looking into the following logs and see if there are any errors:

cat /var/log/nginx/error-nodl.log cat /var/log/nginx/access-nodl.log
