IIS and Two Factor Authenticator plugin white bar

[ntozier]

The Authenticator configuration does not appear to work under IIS.
note: configuration of email works as expected.

Environment:
osTicket 1.15.3.1
webserver IIS 10
PHP 7.3.19

Steps to reproduce and notes:

Installed and enabled the Two Factor Authenticator plugin.
Go to Agent profile.
Click on Configure Options.

Click on Authenticator results in the white bar of doom

Opening the Console I see that this is throwing a 500 error.

PHP error logs do not contain any new entries.

IIS logs suck.

I don't know if this has been resolved or if you want me to start my own issue? Let me know.

@ntozier @JediKev - I just attempted to set this up too and same issue with my server, but it is not iis rather apache. Email 2FA works. Authenticator 2FA does not. Same errors apart from the IIS logs.

Php error:

Good Evening, I'm not sure if the cause is the same, but I was having issues with the OAUTH plugin and the white bar on IIS. I had to add the following to my web.config to correct the white bar issue.

<system.web> <httpRuntime requestPathInvalidCharacters="&lt;,&gt;,*,%,&amp;,\,?" /> </system.web>
I put my findings and how I discovered it in the Best Answer here: https://forum.osticket.com/d/101808-oauth2-issues-reverse-proxy
