Hi @mattcoz

I was unable to reproduce this issue on 2.1.1 using :8080 as port.

And :81

Could you please provide more details?

I am having this same issue. I believe the issue is caused when the secure and insecure are using different ports.

Environment

MacOS 10.12, Apache 2.4, PHP7

Magento Install Script

magento setup:install -vvv --base-url="http://store-dev.test.net:30010/" --use-secure=1 --base-url-secure="https://store-dev.test.net:30000" --use-secure-admin=1 --backend-frontname="the_admin" 

Apache Conf

Listen 30000
<VirtualHost *:30000>
    DocumentRoot /Users/dev/STORE_HOME/src/web/pub

    SSLEngine on
    SSLCertificateFile "/usr/local/etc/apache2/2.4/server.crt"
    SSLCertificateKeyFile "/usr/local/etc/apache2/2.4/server.key"

    ErrorLog /usr/local/var/log/apache2/store-dev_error.log
    CustomLog /usr/local/var/log/apache2/store-dev.log combined

    RewriteOptions Inherit

        Require all granted
    </Directory>
</VirtualHost>

Im not sure what the correct fix for this is. But in the code below if you replace Store::XML_PATH_UNSECURE_BASE_URL with Store::XML_PATH_SECURE_BASE_URL, it all works great.

@mattcoz Any updates on this?

[mattcoz]

Nope, they apparently have no interest in fixing it. I'm no longer using alternate ports.

I'm currently running a local instance of Magento on ports 81 (http) and 443 (https) and am encountering this issue. Admin 404s despite configuration being correct with regards to rewrites/permissions etc.

@ctadlock, your fix works for me too. Changing XML_PATH_UNSECURE_BASE_URL to XML_PATH_SECURE_BASE_URL in isHostBackend() fixes it.

It looks like isHostBackend() should check XML_PATH_SECURE_IN_ADMINHTML and use the secure/unsecure base url accordingly.

This still isnt fixed in 2.3.2. Took me all day to find this post and fixed the problem by using the secure https address in both base urls in the database.
Started by using 8080 as the unsecure which worked until going into admin and getting a 404 error.
fixed by;
web/unsecure/base_url | https://mydomain:8443/
web/secure/base_url | https://mydomain:8443
I hope this has no knock on effects.

We're using docker and we get this as well.

[JacobBrownAustin]

I'm seeing this issue as well on Magento 2.2.11 .
Thanks for the workaround @simon-letch and @tschirmer !

[JacobBrownAustin]

Also experiencing this on 2.3.4 (current latest release).

[Megarushing]

I was experiencing this before using bitnami magento2 docker image, but now I updated the image to 2.3.4 and this issue doesnt seem to be happening anymore, disabled the workaround

The backoffice loads on port 8888, see screenshot.
