I configured a new virtual machine with OnlyOffice only (nginx), configured the SSL certificate and activated HTTPS.
When I try to connect NextCloud to OnlyOffice with https://onlyoffice.xxxxx.com it works correctly.
After, I created a NAT rule on our firewall to forward traffic from pubblic IP:29443 to internal IP:443 and reconfigured NextCloud to access https://onlyoffice.com.xxxxx.com:29443
But I get the error:
[onlyoffice] Error: HealthcheckRequest on check error: cURL error 28: Connection timed out after 60001 milliseconds (see http://curl.haxx.se/libcurl/c/libcurl-errors.html)
