Welcome to the forums. Have you already tried force stop and clear data for the Captive Portal Login app?

Did you restart the phone after clearing data for the app? Sometimes problems with the Captive Portal Login are related to the Android System Webview app, see if these steps work for you.

Not sure what else to suggest. I've seen another thread where a member reported the same problem on the same phone. You could try some general troubleshooting, like wiping the cache partition or booting in safe mode, but there's a chance that the system update included a bug for that specific model.

Found this.

Basically the same troubleshooting steps I mentioned before, cache partition wipe, safe mode and the radical factory reset.

Bad news...I followed all of the steps, I even factory reset. Still not working!!!

I have the same problem with a new Google Pixel 3a with Android 9 (Pie). Same network works nicely with my other mobiles with Android 8 (Oreo). Any suggestions?

One work around I've found is to navigate to a non-secured website, meaning HTTP instead of HTTPS (I use www.weather.com ).

I have a similar issue on my V20 running nougat. The best I can figure is that the captive portal is tripped up by the security of HTTPS sites. For example, using your browser to go to Facebook won't cause the redirect to the Wi-Fi login page, but a non-secured site never fails to redirect. Once logged in to the Wi-Fi, things work normally.

Don't ask me why this happens. On a side note, this work around may get harder over time unless the underlying issue is fixed. One article I read trying to fix my issue said that Google is pushing websites to go to secured HTTPS, and most big sites already do this. I have successfully used the Wi-Fi router's correct ip address (usually 192.168.0.1) to trigger the redirect to the captive portal too.
