Error while connecting Docs and NextCloud

Hi guys!

I’ve tried to connect NextCloud 22 to OnlyOffice Docs. I already installed connector from NC AppMarket.
Then I modified default.json and add secret >
“secret”: {
“browser”: {“string”: “Cloudsecret”, “file”: “”, “tenants”: {}},
“inbox”: {“string”: “Cloudsecret”, “file”: “”, “tenants”: {}},
“outbox”: {“string”: “Cloudsecret”, “file”: “”},
“session”: {“string”: “Cloudsecret”, “file”: “”}

On NextCloud I modofied config.php >
‘onlyoffice’ =>
array (
‘verify_peer_off’ => true,
‘allow_local_remote_servers’ => true,
and added trusted domain domain name and ip of Docs server.

While trying connect Docs to NC I get error “Error when trying to connect (Error occurred in the document service: Error while downloading the document file to be converted.) (version”

Does somebody know how to fix?

Upd. Docs server switched to use HTTPS on 443 port, on NC disabled certificate verification


JWT settings for the Document Server are enabled in local.json config, not default.json.
Please do that and if the issue persists, provide Document Server logs from /var/log/onlyoffice/documentserver/

No, in local.json JWT is disabled.
“inbox”: {
“header”: “Authorization”
“outbox”: {
“header”: “Authorization”
and one more question have I change secret in local.json?
