connectionResetError when finding Subdomain (-d)

[MC874]

Describe the bug
Using "-d" or Subdomain module will result in connectionResetError or Connection Closed by Remote Server or Connection Reset by peer. I think this is caused by incompatible issue with latest python package.

To Reproduce
Steps to reproduce the behavior:

1. Install Vulnx with git clone inside Latest Version of Termux and Package.
2. Proceed to execute install.sh (It will install the latest version of Request and BeautifulSoup4)
3. Run the Vulnx and input it like this :
   vulnx -d http://linebank.com.tw -d

Expected behavior
Vulnx will search subdomain of target without raising exception like image provided below.
