Redirects in SEO Checker does not work

Hi

We are running at Umbraco version 7.5.14 with SEO Checker V1.10.1 and currently, I am trying to fix up redirects.

We have a domain, which points to our IIS servers (loadbalanced).
In this domain, I have 2 pages (test1 and test2), which are setup to be redirected to different pages of our application. Both pages setup is identical, but

test1 is redirected, test2 - is not. Nothing is logged, Umbraco just answers with 404 page. Where shall I look to fix it?

Also, I shall add that all checks initially are done on server, where Umbraco backend is accessible (to exclude possible issues with cache clearing). Also, I did an app restart
