CaptivePortalLogin crashes every time I try to join a network Every time I try to join an unencrypted wifi network that is protected by a web login (e.g. in a hotel), I get a popup message saying "Android System: Sign in to a Wi-Fi network ", I click on this message, and the result is:

CaptivePortalLogin has stopped
Open app again


I have tried also using Firefox or Chrome to find the portal by accessing a random HTTP page or the exact URL that my laptop is directed to to log in.  Firefox returns "Server not found"; Chrome says "You are offline", DNS_PROBE_FINISHED_NO_INTERNET.  My phone is set to not use mobile networks for data.

Is there any way to fix this or is there a workaround?

System information:


Android 8.1.0 (security patch level 1 June 2018)
Nokia 6.1, model TA-1050
Kernel 4.4.78-perf+ (1/6/2018)


EDIT: I've tried a few apps as a workaround, such as Wifi Web Auth in case CaptivePortalLogin is the problem.  This app errors with "Web page not available", ERR_INTERNET_DISCONNECTED, which seems like an odd complaint for an app designed to establish a connection.  Wifi Quick Login fails as well.
Turn off mobile data
Connect to WiFi
