Local Server Login - Endless Redirect Loop

If this is still an issue, would like to see corresponding logs from web and the server so can compare the timestamps - on web enable verbose logging (settings / web / show advanced / debug ) and for Plex Media Server just debug would be sufficient.
I will work on getting this, but it’s a giant pain. To navigate the settings menus you have to hammer the Escape key to stop it from redirecting, which has caused PlexMedia Server to stop responding twice today.

If you’re willing to, you can reproduce this yourself:
1). Navigate to your Plex server in your browser
2). Settings > Server > Network > List of networks that are allowed without auth
3). Add your local IP or IP Mask (i.e. 192.168.1.0/24)
4). Sign out of your account on the Plex Server
5). (Maybe?) Close the tab, open a new tab and navigate to your Plex server again

Going to: http://192.168.1.200:32400/web/index.html
Redirects to: http://192.168.1.200:32400/web/index.html#!/setup/XXXXXXXXXX
And then redirects to:
https://app.plex.tv/auth/#!?clientID=XXXXXXXXXX&context[device][product]=Plex%20Web&context[device][version]=3.39.5&context[device][platform]=Firefox&context[device][platformVersion]=59.0&context[device][device]=Windows&context[device][screenResolution]=1920x943%2C1920x1080&context[device][layout]=desktop&context[device][environment]=bundled&forwardUrl=http%3A%2F%2F192.168.1.200%XXXXX%2Fweb%2Findex.html%23!%2Fsetup%2FXXXXXXXXXX%3FpinID%3DXXXXX&skipSignInUrl=http%3A%2F%2F192.168.1.200%XXXXX%2Fweb%2Findex.html%23!%2Fsetup%2FskipSignIn%3FforwardUrl%3Dhttp%253A%252F%252F192.168.1.200%25XXXXX%252Fweb%252Findex.html%2523%2521%252Fsetup%252FXXXXXXXXXX%253FpinID%XXXXX&code=XXXXXXXXXX

Sorry to have picked up on the setup url
I have reproduced the problem without a first run

Will raise it with the development team

Thanks for the detailed steps
