Using the `HOST` environment variable to specify the IP is deprecated...

Hi everybody.
When I work with Rails, I get this error...

rails s
DEPRECATION WARNING: Using the `HOST` environment variable to specify the IP is deprecated and will be removed in Rails 6.1. Please use `BINDING` environment variable instead. (called from <top (required)> at /home/alex/.disk_a/Rails/GitHub/test_oblako_Github/bin/rails:9)

* Version 4.3.3 (ruby 2.6.4-p104), codename: Mysterious Traveller
* Min threads: 5, max threads: 5

Please tell me how to solve this?

    Hi and welcome to the SUSE Forum :)
    Unfortunately this is for the Enterprise release, you need to head over to (same username/password).

  • excuse me...

    It's not a problem, just you will get better replies to your question over there since it's for openSUSE releases (eg openSUSE Leap 15.1) which is what you are running not SLED or SLES ;)

  • I do not think so.
    'HTTP ERROR 500' after entering login / password.
    I'll be back later when they fix it .... alas, there is no time.

    There was an issue with SSL this morning, can you try again?
