Can't add company 1Password account. #2fa #DuoSecurity

My company has our 1Password account secured with 2FA from Duo Security. I believe this is preventing me from adding my work account to the 1Password app. I have added it successfully to the firefox extension with no issues.

When I attempt to add the account to the 1Password application, via "Manage Accounts" -> "Add an Account" -> "Sign in on 1Password.com", it successfully reads my account data, and populates the window. But after I enter the password for the account, and click "Sign In", it spins for a moment, and then I get:

"We weren't able to sign in to your account. Maybe there's a typo? Check your sign-in details and try again." I know I'm using the correct password, as I just used it to sign into the browser extension successfully.

Checking the logs in ~/.config/1Password/logs, I see the following 3 lines for each time I attempt the sign-in:

ERROR 2021-09-14T08:56:31.214 tokio-runtime-worker(ThreadId(2)) [1P:op-app/src/app/backend/signin.rs:289] error signing in from data layer: UnableToCreateClient(FetchError(post_auth_verify, code: Json, Session ID: B4QHSHZH))

Is this a known issue? I get the same error on both the beta and stable versions.
