Hi,

"Citrix Online Launcher encountered an error:
Error 12029 sending request to server download.citrixonline.com
A connection with the server could not be established."

The above error will be displayed if the Citrix Online Launcher is unable to connect to the appropriate server for a connection. This error will typically indicate either a network or firewall issue, however it can also present itself if the installed Citrix Online Launcher is not correctly updated.

To determine the cause, first remove the Citrix Online Launcher:

Click Start
Click Control Panel
Click Add/Remove Programs, Uninstall A Program, or Programs And Features
Click to highlight Citrix Online Launcher
Click Change/Remove, Remove, or Uninstall

Once the Launcher has been removed, attempt the connection again. If the same error message occurs again, the issue should then be treated as a firewall issue. Reference the following article: http://support.citrixonline.com/en_US...

Actually it was blocked by the antivirus. It seems to work now.

Hi Yves,

Can you please provide more details? Which antivirus program do you use? How did you identify that program was causing the issue? If one of our applications is being identified as a virus we would like to work with the vendor to correct this.

I downloaded the wizard, but could not fix the error 12029, which prevents me from connecting to the server. probably my PC antivirus has blocked it, will appreciate some suggestions on how to fix it?

This reply was created from a merged topic originally titled Error 12029 sending request to server builds.citrixonlinecdn.com.

When trying to connect to a session I'm registered I receive the error Error 12029 sending request to server builds.citrixonlinecdn.com. I can access go to meeting and go to webinar sessions without any problem.

Using windows 7 pro and tried on all browsers.

Please reference the following article: http://support.citrixonline.com/en_US/gotomeeting/help_files/GTM120001?title=Firewalls+and+GoToMeeti... 


However, some customers on unsecured home networks and no software firewalls may still have an issue connecting to our servers or connecting to the internet in general.  A symptom may be "webpage cannot be displayed" in IE.  Other browsers may also be experiencing the same issue, but not necessarily all browsers are affected. 

(Example Solution) In Internet Explorer:
  1. Click Tools
  2. Click Internet options
  3. Click Advanced
  4. Click Reset
  5. Click OK or Reset
  6. Restart Internet Explorer
