通常允许使用每个套接字地址(协议/网络地址/端口)

I'm getting this error sometimes when I try to connect to a mysql database using PHP:

"one usage of each socket address (protocol/network address/port) is normally permitted"

This is the connection string that I'm using:

$con4=mysqli_connect("127.0.0.1","usuario","senha","bd");

I'm using a Windows 10 with Wamp with PHP 5.6.40 and MySQL 5.7.24

I have already changed these regedit parameters to these values:

TcpTimedWaitDelay REG_DWORD: 0000001e (hex)

MaxUserPort REG_DWORD: 0000fffe (hex)

TcpNumConnections REG_DWORD: 00fffffe (hex)

TcpMaxDataRetransmissions REG_DWORD: 00000005 (hex)

One note is that it takes a couple of days to see the errors after I reboot the server.

Any advice is really appreciated!
