Nextcloud is returning HTTP 400 for all document requests

[SysEngDan]

I'm running both Nextcloud and the OnlyOffice Docserver in containers with Docker Swarm.

The admin screen is configured in a way that produces a green validation banner that Nextcloud successfully connects with OnlyOffice Docserver.

When I go to open a document, I get this:

When I check the OnlyOffice logs, I see this output:

I hope someone can please help. I really want to use and endorse this integration but I can't seem to get it working reliably anymore.

Which version on onlyoffice are you using?

Which version on onlyoffice are you using?

(facepalm) sorry. 7.1.1.23 https://hub.docker.com/layers/documentserver/onlyoffice/documentserver/7.1.1.23/images/sha256-8a1edcc13f9d9dd61f3e77bcb172b0f32d0788aa2c63bb5a1206a7633e3dd2f8?context=explore

Hi @SysEngDa, The issue might be with the addresses you specified in the configuration. Could you check if http://files_example_org_php is accessible from inside the Document Server container?

[unnilennium]

same issue here with document server 7.3.0-184 except I have only few documents with this issue. 1- most I am able to open them , 2- few I am never able to open them as they show message "Loading" without percentage 3- and fewer I have this message related with sockjs.min.js:2 (xhr) 400 Bad Request strict-origin-when-cross-origin GET | https://onlyoffice.mydomain.com/doc/1282869996/c/info?t=1675914979694

all of them I can use collaboraoffice/nextcloudoffice

in case of cleaning browser cache completly I get from case 3 to 2.
