Consent Pro

Description

I have just set up Consent Pro V2 on my client’s new Webflow site. We have the Life Time Premium Plan on the account. My client created the account and added me as a user so that I could set it up.

On incognito, I am able to open the Consent Pro by Finsweet app. On my regular window, I receive the “Login failed due to invalid response. Please try again or contact support if this persists.” message. I would prefer this works on my regular window, as every time I switch to Incognito, I need to login again to Webflow via my authenticator and it’s inconvenient.

Site URL

Required: Please provide a staging/production URL where we can see the issue

Steps to Reproduce

The only step really is opening the Consent Pro app. It doesn’t work for me. I have enabled popups in my browser settings as well, with no luck.

Expected Behavior

That the app would let me login and I’d be able to continue configuring the app, checking to see the consent analytics.

Actual Behavior

I am trying to login to my Finsweet account and I am met with the error message that’s in my post’s title.

Additional Context

  • Browser: Version 149.0.7827.201 (Official Build) (64-bit)
  • Device: Desktop

Additional Questions

  • Am I supposed to turn my consent popup into a component and paste it across all pages? Or keep it as a non-component element on the Home page? I am noticing that it’s showing up everywhere which is great.
  • Can you please test and see whether it’s functioning as intended? It’s my first time setting up Consent Pro v2. I used to setup Consent Pro v1 quite often though! Thank you.

Hey @andrewe97! Let me work through each of your questions here.

On the “Login failed due to invalid response” error

This is a known pattern we’ve seen with Consent Pro — works in incognito but not a regular window usually points to either a conflicting cached session or a browser extension intercepting the auth response. Here’s what to try:

  1. Clear cookies and site data for webflow.com and finsweet.com in your regular browser (Settings → Privacy → Clear browsing data, filter by those sites).
  2. Fully log out of all Webflow accounts and any Finsweet sessions in that window.
  3. Temporarily disable browser extensions — especially ad blockers, uBlock Origin, or Privacy Badger. Incognito disables these by default, which is likely why it works there.
  4. Restart the browser, log back into Webflow, then try opening Consent Pro again.

If that doesn’t clear it up, we’ll flag it to @Support-Luis @Support-Pedro to look at the auth logs on the account side — some cases like this need a closer look at what the service is returning for a specific account.

On component vs. non-component

Keep the consent element as a non-component. In v2, Consent Pro manages the banner itself — the key rule is that all elements must stay inside the consent_components wrapper. If you want it truly global without pasting it on every page, you can wrap the outer consent_components div in a Webflow Symbol. Just make sure nothing gets moved outside that wrapper when you do it.

The fact it’s already showing sitewide is a good sign — your setup is working. :flexed_biceps:

On verifying the setup

Your HTML looks correct — fs-consent-version="2", opt-in and opt-out instances, and the consent_components wrapper are all in place. To confirm end-to-end, check inside the Consent Pro app for a green “You are all set” status after scanning. If the Actions tab has any items listed, those are worth addressing.

Let us know how the browser troubleshooting goes! :folded_hands:
