The CAPTCHA response was not verified successfully, please try again.

Hi there AF10 - sorry to hear you're having issues with this.

Can you please walk us through the steps you took to do this and send us a screenshot of the error so that we can have a look too?

Thanks!

I get the same "The CAPTCHA response was not verified successfully, please try again." while simply logging on to Dropbox (Firefox 121.0.1 64-bit on Ubuntu 22.04). No captcha ever appears. It just sits there while the lines move around the animated icon square.

Hi villebillie54, do you have any proxy, VPN, firewall, security software, or even ISP/router settings that could be restricting traffic to the following Dropbox domains, namely the ones involving arkoselabs.com?

None of the above. I had no problems until about a month ago and then this happened. Wait... I just clicked on the shortcut Dropbox icon that I saved on the Firefox home page and it took me straight to Dropbox without even entering my login and password. Weird. By the way I have no problem logging into Dropbox.com when using Chrome or through my Google account on either Firefox or Chrome. Anyway, I found that there multiple ways to log in without worrying about using the Dropbox.com login on Firefox. Thanks for your reply.
