Having trouble with MFA using Yubikeys

We are having issues with using 2FA. We go through the setup and activate it but when you log back in and it askes for the six digit code the page just freezes and you can't click to accept or enter key does not work either. However if I login through my phone the six digit code is accepted. We have tried several computers and they all have the same effect and different browsers. We are using Yubikeys for generating our codes.

Everything is working as it should up until that point. The box that opens up to allow the code works as we are able to type or paste the six digit number in there but the only button that works on the box is the cancel button. We can't move on any further, this is on both Chrome and Firefox and on two different computers. However on my phone it works as it should. I am using Chrome on my phone.

@Rav I setup 2FA through Google Authenticator and by using SMS and have both produced the same result. I can set it up and it takes the initial six digit code but when you log back in it will not allow me to continue past the authentication box. The continue button lights up when you click on it but it does nothing. 2FA still works on my phone thankfully so I can undo it as if this was not the case we would have no access to our accounts.

Yubikey is a hardware 2FA device that plugs into the USB port and has software that reads the QR codes off the screen to add them to the memory in the key. It then generates the six digit code. I have several other software vendors setup in my key and they all work fine instead of using Google or Microsoft Authenticators.

@Rav I setup 2FA with Google Authenticator and ran Hosted in incognito mode on Chrome and it worked as normal. I tried it with Firefox private window and it worked as well. I cleared that 2FA setting and reconnected it to my Yubikey and tested and both browsers worked ok while in incognito and private browsing.

I then disabled all the extensions in Chrome and tried it again but unfortunately it will still not accept the six digit code even with everything turned off. My second computer has less extensions on Chrome and it still won't work on there either with extensions disabled. This is with both Google Authenticator and the Yubikey.

We have managed to come up with a different solution to get around the 2FA issue with multiple users using the same login. We were in the same boat as other pe

We have tried authenticating via every means and it still will not work, with or without extensions enabled, on two different machines and different browsers, incognito mode is the only way it will work.

@Rav Just for information, I tried our login on another computer and laptop and both failed at the same location where you can't continue after entering the six digit code. I don't think is related to our office computers it has to be some incompatibly somewhere else.
