"Failed to Sync to Trello Server" Error Message
Asked by Mckaylah Wade:

Over the last few days I've been getting a "Changes not saved; failed to sync to the Trello server" error message.

I updated my Account to Atlassian per Trello's request and have been having issues connecting ever since. I have disabled extensions, cleared my caches and restarted my computer many times without success.

Any help would be greatly appreciated!

We're looking into this issue right now and trying to figure this out. *Somehow*this issue was resolved for Mckaylah, but we're not really sure how, and not yet sure what's causing it. I'm digging into this today and will update this thread once we figure it out.

Thanks for the patience, and sorry you're facing this issue!

body: Mine actually magically solved itself as well. I had opened Trello on my personal computer and didn't have any issues, so I edited a few cards as a test. Then when I went back to work computer, everything seemed find. Can't say that these two things are related, but I am no longer having the issue.

Free to answer your questions,   
thanks a lot,

body: I am also having this same exact issue (along with a couple teammates) and we have no idea how to resolve. Has there been any further updates?

body: Also having this same problem! Is there a way to fix it?


author: Felix
body: [@Lauren Bernstein](/t5/user/viewprofilepage/user-id/4180433) we think we've resolved this issue, and it should no longer be happening. Are you getting the exact same message? ("Change not saved: failed to sync with the Trello server.")

If so, please reach out to support so we can diagnose this issue with you.

From what I can tell based on Trello's logs, the variation of this problem that was reported mid-November is no longer occurring.

Thanks,

Felix

body: I just started having this same problem this morning on my work computer. I did also do an update this morning (not sure exactly what, just whatever it prompted me to do), so that could be a factor, but I've tried everything I know to do, and still have the same error in the picture posted above.

Also, we had an outage today so any experience you had today would have been because of that.

It's unlikely to be related to the Atlassian account.

comments: author: Mckaylah Wade
body: I have been using Chrome!

Sadly, I've been having this issue before the outage occurred today and I am still having it after.

body: Can you pop open an incognito window and use that for awhile and see if the problem persists?


author: Mckaylah Wade
body: Hmm, it still does not seem to be able to connect even in an incognito window? I did submit a service request as well to hopefully help resolve the issue.![Trello Issue.PNG](https://community.atlassian.com/t5/image/serverpage/image-id/118516iB70C5AA9A58D3EAE/image-size/large?v=v2&px=999 "Trello Issue.PNG")


author: Michael Pryor
body: Do you have Power-Ups turned on for this board and which ones?

Does this persist if you are looking at a board \*WITHOUT\* those Power-Ups turned on?


author: Mckaylah Wade
body: The only power-up I had enabled is "Calendar". If I disable it - it still says "cannot connect to server"


author: Michael Pryor
body: And if you create a new board, same result? (all in incognito window)


author: Mckaylah Wade
body: Yes, same result.

body: Hello Mckaylah,

Hello Michael,

I have the same issue, and it's been a week now. I have the exact same caracteristics than mckaylah. I can log into the apps, on a android phone and an android tablet, and trello computer sees the changes i made from tablets instantanely. But I can't modify anything from my computer, either on Chrome or Firefox. Any idea ?
