Secure HTTPS protocol between NGINX reverse proxy server and VestaCP server

[TurbOS]

Hello dear friends!

I have two servers.
The first server (let's designate it as server A) is the NGINX reverse proxy server on the CentOS 7.X system. Its conditional IP address is 173.176.183.183.
The second server (let's designate it as server B) is a fully functional server with a VESTA panel on the CentOS 6.X system. Its conditional IP address is 93.151.75.75.
Some sites, such as website1.com, work directly with the client via the secure HTTPS protocol.
The question is, how to properly organize the work of clients over a secure HTTPS protocol between server A and server B when accessing websites2.com and website3.com?
Since the SSL certificates obtained earlier for these sites, I will now have to install them on server A.

I will be very grateful if you tell me the configuration of the NGINX settings on server A and the correct settings for server B.

Thanks in advance!

VestaCP is vastly outdated and exploited with no security patches or updates for a long time now.

I suggest you to use HestiaCP, fork of VestaCP that is also open-source just updated, with new features and not dead as VestaCP.

I don't know why is VestaCP still up and in options to install with some hosting providers, because it shouldn't be.

HestiaCP is fork of VestaCP and you can check it out on https://hestiacp.com and join Discord for quick support or post on forum.

Most of Hestia developers are from original VestaCP team, so give them a credit and try HestiaCP, donate if you like it and support them.

Best reguards,
Nikola.
