Why does a 301 redirect give an error 400 Bad Request The plain HTTP request was sent to HTTPS port?

Question

Nginx

Good afternoon everyone.
Site on Bitrix. There was a task to change the directory structure a bit, because of this, you need to redirect from several old pages to new ones.
In .htaccess I write the following structure:
Redirect 301 /catalog/opory-osveshchenyia/opory-osveshcheniya-nesilovye/opory-osveshcheniya-ogk/ /catalog/opory-osveshchenyia/opory-osveshcheniya-nesilovye/granenye-opory/

And then if you open the first the address from which the redirect should be, it gives an error:
400 Bad Request
The plain HTTP request was sent to HTTPS port
nginx/1.18.0
At the same time, the address for some reason with http. If you manually change to https, then everything works.

Here is the whole .htaccess
