Resolved Deploy ruby app using Plesk - "Web application could not be started"

[thefibig]

Hi!

I am new to Ruby in general and now I wanted to try the following Ruby app on my server:
Zammad Community | Home & Download

My system:
Ubuntu 16.04.2 LTS
Plesk Onyx v17.5.3

So, I just installed "Ruby Support", "Phusion Passenger server " and "Tools required for building Ruby gems" via the Plesk Installer. Thereafter I did everything as described here:
Manage Ruby Applications

Then I set the database config file and ran "rake db:migrate", "rake db:seed" and "rake: assetsrecompile" successfully. But when I open the subdomain, the website is loading a few seconds and then I get the following error report):

[Attached, because too long]

I also tried to run "bundle install" not via Plesk but it didn't help.

Do you have any idea? What could be a solution?

I was looking for one with Google, etc. for a long time now but I didn't find anything...

Thank you in advance!

Hi thefibig,

incompatible library version - /var/www/vhosts/***/zammad.***/zammad/vendor/bundle/ruby/2.3.0/gems/http_parser.rb-0.6.0/lib/ruby_http_parser.so (LoadError)

Pls. consider to confront the developpers or the providers of your third party software, if you experience issues with it. Here at the Plesk Community Forum, we try to help people with PLESK components and extension issues/errors/problems. I suggest to visit:

Hi!

Ok, thank you for answer. It helped me because I can focus on the third party software now.

Have a nice day!
