The right URL when root is Subfolder

Please am having this problem when the site is on example.com/upload_folder/web/ and I set the agreement url to be /upload_folder/web/ agreement

On edge says "Hmmm...can’t reach this page", on opera "This page isn’t working example.com redirected you too many times. ERR_TOO_MANY_REDIRECTS" and on chrome "This page isn’t working example.com redirected you too many times. Try clearing your cookies. ERR_TOO_MANY_REDIRECTS"

I have the redirect feature on cpanel actiavted, to redirect example.com/upload_folder/ to example.com/upload_folder/web since drupal actual files are in the folder "web"

When I use /agreement displays the existing agreement terms of use agrement on the site at https://example.com/terms-of-use-agreement/ which is not even related and has a totally different use terms.

Error log reports:

when the user tries to login "page not found 10/31/2019 - 03:12 /projectdin/web/terms-of-use"
when admin is saving the agreement page setting "php 10/31/2019 - 03:11 Warning: call_user_func_array() expects parameter 1 to…"

the full admin error prints:

Location 	https://example.com/upload_folder/web/admin/config/people/agreement/manage/term_of_use?destination=%2Fprojectdin%2Fweb%2Fadmin%2Fconfig%2Fpeople%2Fagreement

Referrer 	https://example.com/upload_folder/web/admin/config/people/agreement/manage/term_of_use?destination=/projectdin/web/admin/config/people/agreement
