Issue description

Setting the PROXYHOST and NONPROXYHOSTS parameters to the same single-character value will directly connect to a Snowflake instance and bypass the proxy server, eg: ...USEPROXY=true;PROXYHOST=a;NONPROXYHOSTS=a;PROXYPORT=3128 connects successfully.

If PROXYHOST and NONPROXYHOSTS are set to different or non-single-character values, eg: ...USEPROXY=true;PROXYHOST=ab;NONPROXYHOSTS=ab;PROXYPORT=3128 then the connection will try to go through the proxy server and then properly hangs and waits until timeout is reached.

Driver version: 2.0.22
OS: Mac Intel 13.3.1
.NET framework: 6.0.406
