This problem looks like the case of using `http://localhost` as domain as found the issue:
[magento 2 Error ERR\_TOO\_MANY\_REDIRECTS](https://magento.stackexchange.com/questions/94722/magento-2-error-err-too-many-redirects)

But in my case the base-url is: `http://m2test_bd.mac0004.isaac.local/`

When I make a clean install on this URL and open (in Chrome of Firefox):

`http://m2test_bd.mac0004.isaac.local/admin/`

I get redirected to: 

`http://m2test_bd.mac0004.isaac.local/admin/http:/index/m2test_bd.mac0004.isaac.local/admin/admin/index/index/key/8028086a452629a2b24de1fca7faaa78009a188619fdc2558c10e78f5eb18a0a/`

And get the notice:

```
The m2test_bd.mac0004.isaac.local page isn’t working

m2test_bd.mac0004.isaac.local redirected you too many times.

ERR_TOO_MANY_REDIRECTS

```

Can anyone tell me what I'm doing or is going wrong?
