Sample AIM VB.Net code failing -- error message "A connection attempt failed"

Mike_reph — Sun, 25 Mar 2012 17:34:04 GMT

All -- I do not seem to be able to get ANY of the sample code working against the test or live systems, and am confused what the problem may be. (Note -- very new to web developing).

Specific error message with VB.NET sample code (changed API login id & transaction key):

A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 64.94.118.33:443

I saw somewhere in the forum that someone had a similar issue and that it might be SSL related. My SSL seems ok if you go to https://sitename.com, but if you go to www.sitename.com, you will get a SSL warning. Could this be the issue?

Note -- I'm using a subdomain with SSL, but the top level domain is not secured by ssl...

That IP 64.94.118.33 is secure.authorize.net

Can you get to https://secure.authorize.net/ in a broswer?

Re: Sample AIM VB.Net code failing -- error message "A connection attempt failed"

Mike_reph — Sun, 25 Mar 2012 22:13:37 GMT

Yes, I can access the https://secure.authorize.net/. I'm wondering if https://secure.authorize.net/gateway/transact.dll is rejecting my connection because of how I have SSL set up.

I had (changing this now), SSL set up the following way (which is probably stupid, which is why I'm fixing it).

https://races2run.signup2raceusa.com had the SSL certificate

www.signup2raceusa.com was NOT secured via SSL.

So I'm switching the SSL certificate to the root level domain instead of being in the subdomain. Will test again tomorrow to see if that works.

Still not working. Called Authorize.net support, and am very sad to say that they were almost no help at all.

RaynorC1emen7 — Mon, 26 Mar 2012 23:02:48 GMT

Can you post your code, since it look like you make changes to the sample AIM VB code.

Just make sure you remove your loginID and transactionKey when you post.

RaynorC1emen7 — Mon, 26 Mar 2012 23:51:15 GMT

Check if your firewall might be blocking it.

Could be the user on the IIS application pool don't have enough permission

Did the IIS log show anything?

Try do the

myWriter = New StreamWriter(objRequest.GetRequestStream())

to another URL like "http://www.yahoo.com" see if it still error on the same place

if that work try

"https://login.yahoo.com/"

Hi Raynor,

I think you are on to something. I tried the same code, but changed the url to "http://www.yahoo.com" and received the exact same error message...

I am using hosting from 1&1.com, and am engaged with their support folks. I'm suspecting that it might be a rights issue...

Re: Sample AIM VB.Net code failing -- error message "A connection attempt failed"

RaynorC1emen7 — Wed, 28 Mar 2012 18:05:37 GMT

Did some research on my lunch break.

Read the section on Communicating with PayPal Server via a Proxy Server

http://tofuculture.com/Blog/post/Tips-Tricks-of-Using-11-Shared-Hosting-Environment.aspx

and proxy server config for 1&1

THAT WAS IT!!!! Raynor YOU ROCK!!!

Re: Sample AIM VB.Net code failing -- error message "A connection attempt failed"

Mike_reph — Wed, 28 Mar 2012 20:20:03 GMT

So, the solution to my problem is:

change the web.config file to add the proxy server for 1and1.com

<system.net>

      <defaultProxy>
        <proxy usesystemdefault="False"
        bypassonlocal="False"
        proxyaddress="http://ntproxy.1and1.com:3128"
/>
      </defaultProxy>

</system.net>

Thank you to Raynor for the research and finding the solution.
