Trello Desktop App cannot connect to Internet

Jeff Bremer (public)

Since a few days I could not create new cards anymore.

I would receive notification about not being able to connect or somethking like that. Can’t remember the exact error.

I could however change content of cards and move them around.

Just not creating a new card.

I also removed the app from Windows 10, and reinstalled using Microsoft Windows Store, like I did during first install.

Now I receive the error “Looks like we have lost access to the internet”, while my laptop functions perfectly fine for the rest of the internet.

What is going one here?

How can I make the app connect to the Trello servers again?

Was this similar to this?

Overall there was an outage yesterday so maybe you were affected by this? You can check the details in below status page

@Mirek
No, it is not similar.
I mentioned that I am experiencing this problem for a few days now, so the outage of yesterday is some other problem.

I am still experiencing this problem.
I can login to the webinterface and mobile app without any problem.
It is just the Desktop App that is showing this problem.

Mirek

In that case please could you share more precise details about your error (some screenshot would be great also)? Are you able to check with any other computer using the same network if the case would be similar? (This would eliminate network as a root casue) .. Then we would need to focus on your environment and answer some questions like .. Is it possible to reinstall the application and check again if the login problem exist? Did you made any configuration changes on your computer that might affect this (firewall, antivirus software update.. ).

@Mirek,

I can login on another PC which is in the same network/subnet just fine, using the same app downloaded from Microsoft Store.

Removal and re-install has also been performed, because of the mentioned problem.

No configuration change has been made. Maybe some background Windows Update that I don’t know of, but nothing else.

Have you got any other tips?

I can login using a webbrowser just fine.
I can use the rest of the internet without any problem.
I can login using the same Windows App on another PC just fine.
I have removed the app, rebooted, and installed the app again from the Windows Store.
I am using Windows 10 (1909) with all updates.

Does anybody else has this problem too?

Does anybody have anymore tips?

Mirek

Hmm.. There still might be something blocking the connection. Any active Windows Firewall or anything like that (antivirus?). We need to be sure that everything is fine here. Maybe it could be turned off temporary.

I think you should also try to connect your current laptop (that have a problem) to a different network (example mobile hot spot) to see if the app would connect after that.. If not then something might be really wrong with the app and even reinstalling did not help which is pretty odd..

But please check first. And by the way a small suggestion that here on community you can reply to my replies using Reply section (not need to create new separate answers). Thanks to that it would be easier to read this by someone else that might want to help with troubleshooting Thank you.

I tried each of the following actions without good result:

I turned off firewall and antivirus software.
Uninstalled antivirus. Turned off Windows Firewall.
The laptop has been connected to various networks. Even the same in which the PC App functions ok.
CCleaner, while it did not find anything special because this laptop was pretty clean already.

Hi Jeff,

Do you use a VPN? I had a few problems with Nord last month, that I had to contact Nord about for them to send me a fix.

Just a thought

Jeff Bremer (public)

Hi Esme. Thank you for the tip.
I only use a VPN for special cases.
The problem is the same, both with and wihtout VPN .

Esme Crutchley

Hi Jeff,

Oh dear, I thought for sure that would be the cause! I‘ve had soooo many problems with Nord recently and while the fix they gave me yesterday is working on one machine, it’s not working on the other.

It was worth suggesting, just in case!

It might be worth reaching out to Trello support, you can find their contact form here https://trello.com/en-US/contact, if you click on ‘Ask Trello Support’ you’ll get through to a contact form. You can even copy & paste the link to this page in as well so that they can see what you've already tried.

I’m sorry we couldn’t get this sorted for you

so this just happened to me today and I'm connected... is there an outage?

I have the same thing.

I originally had a completely white screen - reloading, restarting, resizing etc did nothing. I used the 'reset local data' from the help menu, which triggered me to login again, only to now have this "Oops, looks like we've lost access to the internet" message. I'm typing this from the same laptop.

I'm using the App on a MacBook Pro running Monterey 12.7.5

What worked for me... I was about to remove the Trello app entirely and reload it from the App Store, when I noticed I was also getting a white screen when loading the App Store. So maybe the Trello app was trying to check for updates and getting stuck by an App Store problem.

Anyway, I logged out of my Apple ID, rebooted, and everything is working fine.

It's a pain having to re-login to my Apple ID, especially since logging out removed my payment cards from my laptop. But it worked.

I am having same problem on Mac App, on MAC Tahoe Version 26.2
