Firefox open problem with Uncaught DOMException: The operation is insecure. sdk-all-min.js:1256

[ischiros]

Hello,
For a few days now, it's been impossible for me to open .docx .xlsx .odt and .ods documents with Firefox.
I have an error message saying "Une erreur s’est produite lors de l’ouverture du fichier" (aka "An error occured during the file opening") :

I use Nextcloud 22.1.1, OnlyOffice 7.2.0 and Firefox 94.0.1
With another browser (Safari or Chrome), there is no error.

[lepus2589]

This happens for me, too. I don't get an error message, but the document editor gets stuck on "Loading Document..."

Nextcloud 22.2.2 Enterprise, OnlyOffice 6.4.2, Firefox 96.0b2, Mac OS X

Browser console shows this:

Uncaught TypeError: sf.o0b is not a function

Hi @ischiros and @lepus2589

I think that your cases are similar, but root case of your problem may be different, so I need some investigation

About @ischiros
Could you clarify version of DocumentServer and installation method, because OnlyOffice 7.2.0 is version of connect
Does this error only happens in firefox or in any browser
Is there any error in browser JS console and if there any error in logs on backed (/var/log/onlyoffice/documentserver)

I think it's better to create a new issue at DocumentServer repo with anserwer to my questions
Your errors somehow is related to fonts, so

1. Do you added new fonts to DocumentServer
2. Does this error happens only in firefox
3. Have you had cleaned firefox cache if you've added new fonts before. Does this error happens in incognito mode

Hello,

I don't understand your question.
I have 3 managed versions of Nextcloud+OnlyOffice. I didn't install them myself, but I have admin access to them. How can I check this ?
It happens only in Firefox. Safari and Chrome are fine. And the problem is still there in Firefox 95 (I've updated today).

How can I check this ?

First of all we need installation method, version and host os
Is it rpm\deb\docker?

I have no idea. As I told you, I didn't install it. I've asked to hoster.

And I forgot to answer to your other questions :

Does this error only happens in firefox or in any browser

Only in Firefox

Is there any error in browser JS console

There is this :
Uncaught DOMException: The operation is insecure. sdk-all-min.js:1256

if there any error in logs on backed (/var/log/onlyoffice/documentserver)

I don't know how to check this.

[ShockwaveNN]

I'm sorry, but without info about version, installation method and if new fonts were added I don't think we could provide any help, this information is crucial

Maybe your admin team will comment it here?

[ischiros]

Yes, that's what I've said :

I've asked to hoster.

[ShockwaveNN]

Ok, waiting for theirs reply

I've moved this issue to DocumentServer repo, since seems it has nothing to do with nextcloud

[ShockwaveNN]

And to be clear - is this issue reproduces on Firefox in incognito mode?

[ischiros]

Yes, it is reproduced.

[ShockwaveNN]

I think it may be related to some incorrect configs or broken font install process (which done on backend) so I'll wait until your admins contact us

Hello,

Solution found !
The problem was caused by the third-party cookies, blocked by Firefox.
To solve it, I disabled Firefox advanced protection for our Nextcloud server. Cf attached.

I guess something changed in Onlyoffice behaviour, because I've had these settings in Firefox for years now.

@ischiros Thanks for your feedback
