AttributeError: module 'ssl' has no attribute 'wrap_socket'

[LeoBeb]

When a client tries to connect to the server using TLS, the following error occurs:

Traceback (most recent call last):
  File "/usr/local/bin/electrum-personal-server", line 8, in <module>
    sys.exit(main())
             ^^^^^^
  File "/usr/local/lib/python3.12/dist-packages/electrumpersonalserver/server/common.py", line 494, in main
    run_electrum_server(rpc, txmonitor, config)
  File "/usr/local/lib/python3.12/dist-packages/electrumpersonalserver/server/common.py", line 147, in run_electrum_server
    sock = ssl.wrap_socket(sock, server_side=True,
           ^^^^^^^^^^^^^^^
AttributeError: module 'ssl' has no attribute 'wrap_socket'

This is because the wrap_socket() function was deprecated after Python 3.7.
I was able to fix this by replacing lines 147-149:

                sock = ssl.wrap_socket(sock, server_side=True,
                    certfile=certfile, keyfile=keyfile,
                    ssl_version=ssl.PROTOCOL_SSLv23)

With the following:

                context = ssl.SSLContext(ssl.PROTOCOL_TLS)
                context.load_cert_chain(certfile=certfile, keyfile=keyfile)
                sock = context.wrap_socket(sock, server_side=True)

After that I was able to successfully connect with my Electrum wallet.
