"Syncing please wait" endlessly on existing spreadsheet since update to 2025.6.0

meaz

When users try to open a spreadsheet, they get a popup with an endlessly message that says something like "Syncing, please wait ("Synchronisation, veuillez patienter" in French is the exact message).
It happens since we updated to 2025.6.0.
It happens only with spreadsheet, no other documents, and only with new ones.

My nginx config was updated as expected.

Hello there!

meaz It happens only with spreadsheet, no other documents, and only with new ones.

Just to be sure what you mean with "only with new ones": are the freshly created Spreadsheet documents created impacted? Meaning that upon creation you cannot access their content?

meaz

Mathilde sorry I meant "only with old ones". No problem if I create a new spreadsheet.

Mathilde

meaz no worries, has it been fixed after applying the following Nginx changes?

dsastre

Mathilde I had the same errors and for me it worked after updating the nginx changes.

I am using the simple Nginx config and am having the same problem. Does the simple Nginx config need an update also?

Mathilde

den hello,

No, it doesn't. It must be another issue. Don't hesitate to open your own thread so we could track this easily and keep things clean. 🙂

I stumbled upon this and the nginx changes did not fix it. I'm building from source and when I start up 2025.6.0 and open a XLS I get errors in the nginx-error.log like:

2025/09/16 12:10:44 [error] 65105#0: *13 open() "/project/cryptpad/2025.6.0-dev/cryptpad-2025.6.0/customize.dist//common/onlyoffice/dist/v7/plugins.json" failed (2: No such file or directory), client: 11.1.3.12, server: devel.de, request: "GET /common/onlyoffice/dist/v7/plugins.json HTTP/2.0", host: "develsb.de", referrer: "https://develsb.de/common/onlyoffice/dist/v7/web-apps/apps/spreadsheeteditor/main/index.html?_dc=0&lang=en&customer=ONLYOFFICE&ver=2025.6.0-1758017421839&frameEditorId=cp-app-oo-placeholder-a&compact=true&parentOrigin=https://develsb.de&uitheme=theme-classic-light"

or more readable:

2025/09/16 12:10:44 [error] 65105#0: *13 open() 
"/project/cryptpad/2025.6.0-dev/cryptpad-2025.6.0/customize.dist//common/onlyoffice/dist/v7/plugins.json" failed (2: No such file or directory),

If I read it right,
/common/onlyoffice/dist/v7/web-apps/apps/spreadsheeteditor/main/index.html
somehow wants to read (GET)
/common/onlyoffice/dist/v7/plugins.json
which nginx translates into
"/project/cryptpad/2025.6.0-dev/cryptpad-2025.6.0/customize.dist//common/onlyoffice/dist/v7/plugins.json"
on filesystem level and which does not exist. Also wondering about the two slashes (..dist//common)
There isn't even a common folder under customize.dist.

So if I check and try to find plugins.json I olnly see one for v1:

cpprj@barbie:/project/cryptpad/git/cryptpad-baremetal> find /project/cryptpad/2025.6.0-dev/cryptpad-2025.6.0 -name plugins.json
/project/cryptpad/2025.6.0-dev/cryptpad-2025.6.0/www/common/onlyoffice/plugins.json
/project/cryptpad/2025.6.0-dev/cryptpad-2025.6.0/www/common/onlyoffice/dist/v1/plugins.json

no more no less under nginx' root /project/cryptpad/2025.6.0-dev/cryptpad-2025.6.0.

I also have error-logs for the editor:

2025/09/16 12:10:53 [error] 65105#0: *13
open() "/project/cryptpad/2025.6.0-dev/cryptpad-2025.6.0/customize.dist//common/onlyoffice/dist/v8/document_editor_service_worker.js"

trying to find this file:

find /project/cryptpad/2025.6.0-dev/cryptpad-2025.6.0 -name document_editor_service_worker.js
/project/cryptpad/2025.6.0-dev/cryptpad-2025.6.0/www/common/onlyoffice/dist/v8/sdkjs/common/serviceworker/document_editor_service_worker.js

This is even more weird, since it is located somewhere under ...dist/v8/sdkjs/common... where no rule in ngingx.conf ever points to.

In my setup I copy the data folder from 2025.3.1/ to 2025.6.0/ and start it up. After login and opening a precious XLS the first sheet gets blanked out and I have a couple of these file-not-found errors in the log. I can edit and save, but the previous contents are gone forever. Since 2025.3.1/2025.6.0 are separated at filesystem/network level I'm able to rerun 2025.3.1 but It's not possible to upgrade without trashing the XLS sheets.

So, for me it looks like there is something wrong with OO-v8 path handling. The stored XLS are v7 and it seems like it wants to convert them.

Alas I must say I changed install-openoffice.sh to install all versions

echo 'oldest_needed_version=v1' >onlyoffice-conf/onlyoffice.properties

since the new default on;y installed v8 and I had a lot of .../v7/.'.. errors in the logs.

I might have a look what happens when I prevent it to install v8.

Anyway, I'm out of options. There is something wrong with updating (!) non-docker installs with old documents from 2025.3.1 to 2025.6.0.

I also face this issue on my docker install. Spreadsheets are broken for me, new and old ones. All other document types seem to work fine.
I have reinstalled all onlyoffice dists and my nginx error.log shows the same errors as Peters.
My advanced nginx config is up to date with the official one. Only change is that cryptpad lives at cryptpad and not localhost and that it does not do TLS, since it is behind another proxy.
It worked fine in 2025.3.0 and I suspect the nginx config is broken in some way.

If wanted I can provide more details.
