MR44|MR46E - Clients are not redirected to the Splash Page

[FayMephist]

Hello, I am having an issue with Meraki Splash page (click through). When clients connect to the Wi-Fi, they are not redirected to the plash page. 

What I found is that the client sent the HTTP Get when connected to the Wi-Fi and received the HTTP 307 Temporary Redirect from the AP successfully. The Splash URL was sent to a client, however, they were redirected to www.msftconnecttest.com/redirect, instead of loading the Meraki page. 

I had to copied the Splash URL below, and pasted it on Edge, so that I could get to the Splash page. After that I clicked "Continue to the Internet", and this client was authorised on Meraki, and internet was working. 

Does anyone have this problem? 

*I had disabled the the Network Connectivity Status Indicator site (NCSI) on this client, but when connecting to the Wi-Fi, the client did not send the HTTP Get to Meraki AP. 

*I also downgraded and upgraded the AP firmware, but it could not help.

The URL  www.msftconnecttest.com/redirect redirects to the MSN website. So it most likely it's the default website of the browser like Edge. 

In the Access Control page for the SSID, there would be a setting "Captive portal strength". You may set it to 'Block all access until sign-on is complete' and it may help to force the device to open the splash page
