# 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) as root.
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
