so how is now handled cancel case? Will it still work?

I just worry if we do not break working scenario like registration on running system.

If I'm not wrong that was mainly for slp discovery but we are even not using it as we are always using the custom_url

yast-registration/src/lib/registration/url_helpers.rb

Line 79 in 916acb6

return url if url == :cancel

yast-registration/src/lib/registration/url_helpers.rb

Line 116 in 916acb6

return custom_url if custom_url && !custom_url.empty?

yast-registration/src/lib/registration/widgets/registration_code.rb

Line 56 in 916acb6

options.custom_url = default_url

The current problem is that we are using always the cached url once obtained, other solution could be resetting the cached url before fetching it:

yast-registration/src/lib/registration/url_helpers.rb

Line 88 in 916acb6

def self.reset_registration_url
