net/http: TLS handshake timeout

[imohsen]

Hi
we have a few servers in Iran and you know that internet connectivity , special on tls/ssl connections , are not stable in my country . now our directadmin control panel was refused to work because it's unable to make a POST request to "https://licensing.directadmin.com/start" .
i can reach this url from bash inside the server ( got a html page page ) but when i tried to restart directadmin service it's unable to made this request .

Reason: request failed: Post "https://licensing.directadmin.com/start": net/http: TLS handshake timeout

directadmin[1056252]: 2022/10/08 19:23:39 error license check failure     error=request failed: Post "https://licensing.directadmin.com/start": net/http: TLS handshake timeout

i think about two possible scenario .
first one is to put a web proxy in front of this servers and send request to proxy servers then contact directadmin license servers . is it legal ?
second one change tls version of whatever language directadmin using to 1.3 and restart service . tls connection using tls v1.3 does not manipluate and it's connected but i don't know what language directadmin wroted by . ( from net/http package it's maybe ruby or go but i'm not familiar with this two language and i don't know how to manipluate tls version with this )

would you please help me if you have any other solution that make this server and control panels working again ?
