Unable to log into Dropbox App. "Previous sign in interrupted. Please try again"

I am having the same problem on a windows 10 . This is personal account of Dropbox. Please note that my phone version is working.  I can also sign in on my chrome browser.

I have spent nearly 6 hours with the support bot. I have Norton360 and have reviewed and changed the Smart Firewall settings  and have deleted and reloaded Drop box with the offline installer 3 times. Routers rebooted and refreshed, desktop powered down and up and down and up for a time

I was having the desktop app tell me that  “net::ERROR_NAME_NOT_RESOLVED.” which has gone away with the change in the firewall settings and replaced with crickets.

I am about to move to another product as this is crazy

I reviewed other comments and noted that Duck Duck Go was found to be some problem. SO I dropped it and no joy.

I have replied to Megan on the email and it keeps coming back.  I have replied to her here and she says I have yet to reply.  Idk what else to do.  It is so glitchy, even trying to reply on here is giving me fits.  

Thanks for reporting this here, MikeDyr, and I’m sorry to hear about your experience. 

Can you clarify what settings you changed exactly on your Smart Firewall? Can you try disabling it for a little bit, in case you haven't already, and restarting your device then?

If that doesn't help either, I'd like a screenshot of the crickets you're seeing now.

I’ll be able to further assist this way.

Hey Abrahamconstruction, I just checked your ticket and I can’t see your reply to Megan either. 

Can you please clarify what you mean when saying that it’s coming back, or send me a screenshot of what you see instead after responding to her via email? Just make sure your email address isn’t visible in your screenshot.

Don't get your hopes up, Support just transferred me to some bot that keeps asking me to repeat steps I've already taken. I don't think we're going to get any real help here.

Hey shawnedrei, thanks for your feedback here.

From what I can see, your case was sent to our specialists.

If you have any concerns or need further assistance, please make sure to continue working on the issue with the agent you're in contact with.

They'll be able to provide additional troubleshooting steps and info for you and hopefully your issue will get resolved really soon!

We appreciate your feedback, though, and I'll make sure to pass your comments along to our team.

Hannah​ The "agent" I'm in contact with has now twice asked me to repeat steps I've already attempted to address the problem, despite my literally providing a complete list of everything I've tried both here and in the e-mail chain - and there are two other people on this thread with the exact same problem that Support hasn't been able to help. Either I'm talking to Clippy or your specialists need to wake up.

I shutoff the Norton firewall rebooted and tried to link desktop Dropbox but it failed in the same loop as below. Then I went in and made sure that all Dropbox related service were set to ALLOW. Saved, then rebooted.  Tried again to link desktop Drop Box with the same failure.

Loop

The screen displays Welcome and sign it. Press sign in with Dropbox . Then the "Login successful" screen shows for a second followed by third screen appears stating "Previous sign in interrupted".  If you try again it just loop back to the this screen.

If you try to exit you are informed you should try again. If you do you loop back though all three screens.

I checked the post 17600 17603 are open and Norton is no blocking them
