Document Server Integration Edition behind HAProxy and SSL Certificates

[slater0013]

Bug or Config Issue ?

I've installed Document Server Integration Edition on Debian. I plan to configure a cluster of 2 Document Servers with HAProxy in front like described here : https://helpcenter.onlyoffice.com/fr/server/developer-edition/linux/install-cluster.aspx

In HTTP, everything works fine. But I want to connect Document Server to my NextCloud instance which is runnning in HTTPS.

I configured HAProxy as an SSL Termination, with correct certificates. The communication between HAProxy and OnlyOffice Document Server can stay on http/80 but the Nginx engine on Document Server is forcing fall back to HTTP protocol.

Possibles workarounds would be to let SSL traffic flow through HAProxy to the Document Servers configured in SSL mode, or to decrypt SSL in HAProxy and crypt again communications between HAProxy and Document Servers.

But in my configuration, I use the same HAProxy for Nextcloud and OnlyOffice, and Nextcloud is configurable to let the http mode to HTTPS even if communication between HAProxy and PHP Instances stays in clear HTTP.

Hope I make myself clear !
