Redirect to https to https://site.ru:80?

Question

1C-Bitrix

Good afternoon! It costs nginx and bitrixVM

When accessing via http, a redirect to https occurs, but port 80 is added at the end of the address and as a result an error appears ( https://site.ru:80 )

When connecting to www.mr-group.ru:80 An error has occurred. SSL received a record that is longer than the maximum allowed.

Error code: SSL_ERROR_RX_RECORD_TOO_LONG

Tell me how to remove the addition of the port at the end of the address. Thanks in advance
