Unable to Log in with Metamask

[walidmujahid]

When attempting to log in to the 3box hub with MetaMask, a model appears asking me to approve the message, but no message or MetaMask window opens for me to approve or sign anything:

Opening the Console, I see that I have a:
backend.js:6 "WARNING! Head hash didn't match the contents r @ backend.js:6 (anonymous) @ Store.js:285

and

backend.js:6 TypeError: Cannot read property 'verify' of undefined at keystore.js:208

Near full log here:

3box.io-1581040075318.log

This had been happening on the stable Chrome version previous to 80.0.3987.87 and it is still happening once I had updated to 80.0.3987.87.

My previous MetaMask version was 7.7.3, but I force updated it to 7.7.4 and the problem still persists.
