Not able to sign in in FBA from out side the server.

Question

Hello All,
I have created https enabled web application and sitecollection using power shell. After creating web application, I have enabled claimed based authentication using below mentioned code :
$wa = get-SPWebApplication https://tenant-test02.mydomain.ch
$wa.UseClaimsAuthentication = $true
$wa.Update()
I have enabled FBA on my sharepoint foundation 2013. I am using default login page for login mechanism. While accessing pages from the SharePoint server, login mechanism works successfully. But when I am trying to open same site from out side the network,
it shows the login page but its showing error message when clicking on "Login" button.
From the co-relation Id I am getting below error message.
"Cannot get Membership Provider with name "mycutomprovider". The membership provider for this process was not properly configured. You must configure the membership provider in the .config file for every SharePoint process"
Any suggestion ?

Hi Suhil,
According to your description, my understanding is that the error occurred when you accessed the site with FBA from outside.
Did you add the membership provider settings to the machine.config or to each web.config files?
If not, please refer to the link below to implement this:

If you access the extended web application from outside, then please check if the extended zone has been configured to use the form based authentication.
