NOTE:
I have tried all these methods shown below but none of them worked
Why requests raise this exception &quot;check_hostname requires server_hostname&quot;?

I think the issue is with your proxy, can you please try below commands in your docker container:
export HTTP_PROXY=http://x.x.x.x
    
export https_proxy=http://x.x.x.x
    
export HTTPS_PROXY=http://x.x.x.x
    
export http_proxy=http://x.x.x.x

Change x with your proxy ip
