Problems using SSL

Stefan · **Posted:** Tue Jul 11, 2006 7:23 am

Hello,

first I tried to use the Dynamic Web Twain on a server without SSL.
I used those settings:

f.DynamicWebTwain.HTTPPort = 80;
f.DynamicWebTwain.IfSSL = false;

Everything worked fine. After running the server with SSL, I changed the port to 443 and set ifSSL to true. This returns the following error:

-15029: Die Serververbindung konnte nicht hergestellt werden!
(-15029: Could not connect to server!)

Here is some code that calls the function HTTPUploadThroughPost:

Code:

var strActionPage = "/SaveToFile.php?namepk=abc";
var strHostIP = window.location.hostname;//the host's ip or name
var strImageName = "dummy.jpg";
var f = document.form;
f.DynamicWebTwain.HTTPPort = 443;
f.DynamicWebTwain.IfSSL = true;


var p = f.DynamicWebTwain.HTTPUploadThroughPost(strHostIP, 0, strActionPage, strImageName);
if(!p) {
alert(f.DynamicWebTwain.ErrorCode+": "+f.DynamicWebTwain.ErrorString);
return;
}

Could anyone please support me to make this work on SSL?

Best regards,
Stefan

Hi Stefan,

Your code is correct.

It is possible 443 port is blocked by your firewall. Can you open a https page on the same server from your browser?

Thanks.

Hi Catherine,

I can browse all other SSL-secure pages on this server, even port 443 is not blocked (told me the admin). I really have no idea what could be wrong with the server or the code of the site...

Best regards,
Stefan

I can not see the problem so far.

But I am a littlle confused with your previous posting: "even port 443 is not blocked". Do you mean "even port 443 is blocked"? But if the port is blocked, SSL request can not get through. Would you please clarify it for me?

Also, does your web server have a public IP? If yes, would you please send the URL of your Web page to twainsupport@dynamsoft.com, so that we can connect to your server to look into this problem.

Thanks.

Hello again,

we just solved the problem. It was no problem with the web twain itself. Our webserver wasn`t able to resolve his servername to the correct ip and posted the scanned images to another server. We found this bug, because we got some trouble by reading from the same server via SSL.

Thanks for your support,
Stefan
