ESET Bridge DNS resolve issue

[sdnian 6]

I've an ESET PROTECT v10.0.1128 and ESET Bridge 1.0.37. All clients  use this proxy server. 

After the antivirus software been installed, it can't been activation. I found some logs..

Access.log:

172.1.3.51 - - [04/Feb/2023:15:19:19 +0800] "CONNECT edf.eset.com:443 HTTP/1.1" 502 150 "-" "-"

Error.log:

2023/02/04 16:03:24 [error] 6892#7452: *954 proxy_connect: edf.eset.com could not be resolved (2: Server failure), client: 172.1.3.211, server: , request: "CONNECT edf.eset.com:443 HTTP/1.1", host: "edf.eset.com:443"
2023/02/04 16:03:24 [error] 6892#7452: unexpected DNS response for edf.eset.com

I run a test in the ESET PROTECT server.. Get 502 error.

> curl.exe --proxy hxxp://172.1.3.105:3127/ https://edf.eset.com/edf 
curl: (56) Received HTTP code 502 from proxy after CONNECT

But if don't use proxy.. the connection is fine.

> curl.exe https://edf.eset.com/edf 
<?xml version="1.0" encoding="utf-8"?><ecp:message xmlns:ecp="hxxp://www.eset.com/2012/02/ecp"><ecp:response><code>20101001</code><message>invalid http method</message></ecp:response></ecp:message>

So.. how to fix the Bridge DNS resolved problem?

Thank you!

Sorry... The problem is fixed. It's the primary dns server in the ESET PROTECT server don't work.
