One of my GMail accounts gets an error when I try to setup OAuth2 (other accounts are working).
When using Web Browser (code) I get the following error:
Access blocked: POP Peeper’s request is invalid
XXXXXXX@gmail.com
You can’t sign in because POP Peeper sent an invalid request. You can try again later, or contact the developer about this issue. Learn more about this error

Error 400: invalid_request
When using Web browser I get the following error:
POP Peeper could not initialize this method (possible reason: older OS's need to run as admin). It is recommended that you create an App Password instead of using Oauth2 on this device. Press OK to open Google help page.
I am running POP Pepper as administrator (Windows 10).
I know it can be confusing, but each service has their own restrictions on which methods are supported that aren't currently baked into PP's logic. So, to narrow it down in your case:
- Gmail *only* supports the "web browser" method ("code" and "embedded" will not work)
- The "older OS" message typically applies to end-of-life OS's (e.g. Win7); Win10 should work without running as admin. (and when it suggests "running as admin", that usually means right-clicking on poppeeper.exe and selecting "run as administrator").
OK... so, most likely what's happening is that something on your computer is blocking the default method. This method requires the use of a kind of temporary server on a specific port of your computer (but it should be noted that this data is sent directly from your webbrowser to the local port) and it's possible that something else running on your computer is blocking this. Try disabling any real-time security software you have running (temporarily, until the Oauth2 process says it was successful) and see if that works. Let me know if it does, and if you know specifically which software caused the block.
I turned off the virus protection and still getting the same error. I set this Windows 10 Pop Peeper up using the data from my previous Windows 7 install. I went back to the previous computer and the OAuth2 setup works on that one.
Are you running any other kind of security programs? I'd say something more along the lines of a software firewall? (a hardware firewall wouldn't be relevant). Windows firewall shouldn't be a problem unless you've made custom modifications. Otherwise, try rebooting your computer.
Not running any other security programs and just running the basic Windows firewall. Is there a way to export the client from the Windows 7 setup and import it into the Windows 10 setup?
Sorry for the late reply but I was only just now able to restart my computer. That must have been the issue because it worked after the reboot. Thanks for your help.
