Stuck "syncing changes, please wait"

jdownie

I have an OnlyOffice spreadsheet that i've been using in CryptPad for a few weeks. Today i'm unable to open it. The browser page gets stuck with a spinner displaying "syncing changes, please wait".

I have checked the javascript console, and i find...

chainpad.dist.js?ver…0-1721038820443:821 [anonymous] Error in onSettle handler [TypeError: Cannot read properties of undefined (reading 'focus') at addTabListener (https://cryptpad.downie.net.au/common/common-interface.js?ver=2024.6.0-1721038820443:584:26) at UI.openCustomModal (https://cryptpad.downie.net.au/common/common-interface.js?ver=2024.6.0-1721038820443:624:9) at saveToServer (https://cryptpad.downie.net.au/common/onlyoffice/inner.js?ver=2024.6.0-1721038820443:570:42) at https://cryptpad.downie.net.au/common/onlyoffice/inner.js?ver=2024.6.0-1721038820443:620:21 at https://cryptpad.downie.net.au/components/chainpad/chainpad.dist.js?ver=2024.6.0-1721038820443:920:13 at Array.forEach (<anonymous>) at settle (https://cryptpad.downie.net.au/components/chainpad/chainpad.dist.js?ver=2024.6.0-1721038820443:918:14) at sync (https://cryptpad.downie.net.au/components/chainpad/chainpad.dist.js?ver=2024.6.0-1721038820443:948:9) at https://cryptpad.downie.net.au/components/chainpad/chainpad.dist.js?ver=2024.6.0-1721038820443:908:70 at https://cryptpad.downie.net.au/components/chainpad/chainpad.dist.js?ver=2024.6.0-1721038820443:832:9]

Hi,
I have run into the same problem. It got stuck on "syncing changes, please wait" when trying to open a onlyoffice document. It did not disappear, even when changing browsers.
The instance I am using is self-hosted: https://cryptpad.digitale-kunstfabrik.de/

Now I got it running again, but the "solution" is not satisfying: restarting the pm2 process of cryptpad on the server.

Best,
Matthias

The same error happened to me with a calc sheet at https://cryptpad.piratenpartei.de/sheet/

After the following message nothing happens and the sync screen gets "stuck":
