We seem to have posted in parallel. Here is another thread about probably the same error:

can you try the following

open your onlyoffice url in your browser (not your nextcloud url!) and disable all script / add blocking features of your browser for that onlyoffice-server url.

I suppose the so called …Analytics.js is blocked and it is not a problem of the onlyoffice app 10.1.0 (but more a problem of the latest documentserver 9.4.x)

When done so, re-open nextcloud and try again to open onlyoffice by using existing or new documents.

have a look at this github issue

and this community post

cheers

P.S.: for test purposes you can try to open nextcloud in a private / inkognito window and test if the onlyoffice behave the same.

@ theking2

Could you please check the logs and get the same error (…/AppInfo/Application.php … could not boot document server…) as mentioned in the other thread?

After a bit of digging I found that I was looking in the wrong direction. Debugging the Service Worker for OnlyOffice reveals that a (new?) js file Analytics.js was generating 404 errors. The file does exist on the server. Than (with a bit of help from OnlyOffice forum AI) I found the culprit being uBlock Origin triggered by the name “Analytics”. Adding this line to uBlock Origin File Filter list finally allowed the proper JS library to be accepted:

@@||kingma.ch^$document

In my case both cloud and office run in a domain ending in kingma.ch.

EDIT: although this did work on one (Fedora44KDEPlasma) workstation it did not on another. Apparently uBlock origin does not allow whitelisting a domain with all subdomains it is required to open a link on both a the nextcloud server and click the Big Blue disable ublock on/off button on both the cloud and office sites.
