Description

Hi, I updated from version 1.12.6 to 1.13.6 and have the following problem now.
My gitea is configured for HTTPS and my submodule is added via SSH.
From the main repo the link to the submodule is only HTTP so I can't access
my submodule from the web UI. In version 1.12.6 this worked as expected.

See below some informations:

$ git config --file=.gitmodules -l
submodule.terraform.path=terraform
submodule.terraform.url=gitea@172.16.4.20:steled/terraform.git
submodule.terraform.update=rebase

The web gui is showing http://172.16.4.20/steled/terraform but should show https://172.16.4.20/steled/terraform

SSH_DOMAIN = %(DOMAIN)s
PROTOCOL = https
DOMAIN = ***.duckdns.org
HTTP_PORT = 443
ROOT_URL = %(PROTOCOL)s://%(DOMAIN)s:%(HTTP_PORT)s/

When I manually set SSH_DOMAIN to 172.16.4.20 the WebUI shows https://***.duckdns.org/steled/terraform and the clone link shows gitea@172.16.4.20:steled/terraform.git

Would be great if you can have a look at.

Thanks and best regards
