Error when trying to connect (Bad Request or timeout error)

I followed instructions from http://helpcenter.onlyoffice.com/server/linux/document/linux-installation.aspx and then I followed the instruction to activate the ssl encription and now the documentserver is listening correctly on thee 443 port with ssl encryption

Now I want to integrate nextcloud with onlyoffice. I’ve successfully installed in other machine nextcloud with ssl support I installed and activated the ONLYOFFICE app, into NEXTCLOUD, but when go to configure the app inserting https://<ipaddress-of-onlyoffice-documentserver>/ I have an error that appear to the upper part of the browser

Error when trying to connect (Bad Request or timeout error)

and the integration doesn’t work.

Any idea?

Hello @jaschrock, this error means that the Document Server cannot download the file for editing. It seems that your NC is not accessible for the Document Server.

Check if JWT is disabled in /etc/onlyoffice/documentserver/default.json in container with Document Server, if you do not use it in NC.

Try also to change the value of the following string in default.json from true to false: "rejectUnauthorized": true

Hello @stone212,

Please try to check the accessibility of the Document Server from the machine with Nextcloud and vice versa. Use wget command: wget https://document_server_address and from the machine with Document Server: wget https://nextcloud_address
