magento 2.0.2 admin page ERR_TOO_MANY_REDIRECTS

[optoma]

Is there any suggestion for this problem?

I installed magento2 on 2 production servers  with different domain names

one  is ok

the other admin page will display ERR_TOO_MANY_REDIRECTS

I used the same setting and installation process.

when I use php bin/magento setup:store-config:set --use-secure-admin=0 and it works

but I need to enable SSL for production, so, I can't disable the SSL

any recommendation?

What web server do you use?

Did this get resolved?  I am having the same issue.  Clean install to a development web site of Magento 2.0.2 - I can see the main (customer) page of the shop, but get the ERR_TOO_MANY_REDIRECTS when I try to go to the admin page.  

My website URL looks like this:  http://mywebsite_com.apache4.cloudsector.net/shop/Admin  after entering that, I get the error, and the URL looks something like this:  http://mywebsite_com.apache4.cloudsector.net/shop/Admin/http:/index/mywebsite_com.apache4.cloudsecto...

My webhost is unable to figure out the issue.

Thanks.

As you have installed Magento 2 into a subdirectory, you should adjust your webserver: https://mage2.pro/t/260

Thank you.  I found all 4 .htaccess files and added the two lines - changing /store/ to /shop/ but I am still having the same problem.

Problem solved!  Turns out Magento doesn't like underscores _ in the URL.  Changed underscore to a dash in mywebsite-com and all is good.
