Hello.

What do you mean by the "...directly on ISS" in the topic title?

Do you mean IIS (Internet Information Server) (not ISS?)

If so, I do not believe you are actually using it, or at least the certificates do not come from those tests. It looks like you are confused about what you are doing and testing. The name of certificate, derived from the process name of IIS would be different, certainly not "CGI + FastCGI" again, as with the Apache server.

As with any other case, I can try to set up a reproducible scenario here. But for it I would have to know reasonable well what you are doing.

Regards

we call quickOPC in this way

$opc = 'opc.tcp://192.168.0.180:4840';
$db = 'nsu=http://www.siemens.com/simatic-s7-opcua ;ns=3;s="DB180_UPPERCOM_OPCUA"."%s"."%s"';
$Client = new COM("OpcLabs.EasyOpc.UA.EasyUAClient");
print_r($Client->ReadValue($opc, sprintf($db, 'JobStatusInfo', 'IdentificativoLavorazione')));
print_r($Client->ReadValue($opc, sprintf($db, 'JobStatusInfo', 'JobStatus')));

but go in timeout
this is log error

PHP Fatal error: Maximum execution time of 30 seconds exceeded in C:\inetpub\wwwroot\test2.php on line 8
