Can you maybe share the splash page settings of this SSID? "net::ERR_TOO_MANY_REDIRECTS" is in my opinion related to an issue with the splash page you created.
The error indicates that the browser is stuck in an infinite redirection loop. An infinite redirection loop happens when you visit a URL pointing to another URL, which points back to the first one.
After several redirects, the browser breaks the redirection loop and displays the "too many redirects" error message.
