Connect-PnPOnline -UseWebLogin fails, login window disappears
Have you tried amending your hosts file?
You're a lifesaver, Deleted. I saw that fix from Paul Ryan online, but I neglected to try it. So in response to your post, I added this entry to my hosts file:
127.0.0.1 msoid.summitservices.us.com # fix PnP connect problem
where our domain is summitservices.us.com. I connected first time without an authentication dialog (since I'd already set up Windows Credentials). I ran a few other applets as a quick test, all successful.
You definitely solved my main problem, but I tried to connect again using -UseWebLogin with the same result: quickly disappearing window. The mystery remains.
KenStewart did you ever get this working? I tried, I think, as you said, I turned IPV6 off, I set Google 8.8.8.8 and 8.8.4.4 as my DNS and I logged on to my VPN (I work 100% remote), and all are doing exactly what you are having, my prompt for -UseWebLogin
Connect-PnPOnline -Url $SiteURL -UseWebLogin
Below is a screenshot from a video I took of it. I tried to uninstall and install it again (PNP) as it happens on my user account and on another account that I tried (my admin account).
Just like you, the prompt comes up for a millisecond and then goes away. I have put in my HOSTS file
127.0.0.1 msoid.summitservices.us.com # fix PnP connect problem
and restarted as I tried right after putting that in. I am on a Windows 10 system and I am running PowerShell v5.x as Admin. I tried with PowerShell v7 as well. All the same.

Matthew Carter I never could get that to work and eventually took a different route using the SharePointOnlinePowerShell module. I was able to connect using an administrative account with Connect-SPOService -Url https://MYDOMAIN-admin.sharepoint.com. This brings up the web-based login window, which stays up.
I've been pressed on other projects since that limited success, so haven't pursued things further. I wanted to supply login credential in a script to avoid interactive logins, but never got that far. Let me know if you have any success along those lines.
KenStewart I was having a similar issue but I deleted all the temp files and cookies in IE and then it started up. Hope it helps!
- Happy to help 🙂
When -UseWebLogin quickly disappears, could it be you are already authenticated.
If you run Get-PnPContext it should give you that info.Looks like that's not exactly it, but there are more clues.
I opened a new PowerShell session and ran Get-PnPContext just to make sure there was no connection; returned an error saying I needed a connection first. I ran connect again with the web option, and the window still disappears. However, this time I asked for the context again and I was authenticated.
Apparently, something is bypassing a web dialog and trying a different authorization mechanism, which now succeeds because of the hosts configuration. To test this, I tried to connect to a different site that I hadn't configured with Credentials Manager; failed saying needed connection. Ran again with web option, window disappeared, but no error. Get-PnPContext then showed the new site.
Interesting, but still a little mystery? Isn't -UseWebLogin supposed to bring up a dialog to enter username and password?
- It is, but it sounds like it already has authentication credentials.
Does it still happen after clearing all web cache, cookies etc?
