Hope I can post this as Chrome keeps complaining this site has a data breach.

I have been using NGINX to route my 443 traffic for two servers for a while now. Now I can't get my RDP side of things working. Not sure why as it used to work. RDP is thru Essentials Server 2016 and it's Remote Web Access. I can get to the website but when I try to pull up one of my servers it fails. So the website works, the second server I'm using on 443 works, but not the RDP side of things. it does work if I remove NGINX and set 443 to route directly to the Essentials Server thru my router so know it's working still. What I get in the error logs when this happens is:

2020/09/28 05:09:50 [crit] 7556#7556: *1366 SSL_do_handshake() failed (SSL: error:1417D18C:SSL routines:tls_process_client_hello:version too low) while SSL handshaking, client: 107.6.171.130, server: 0.0.0.0:443

Thoughts?

Thanks.
