Citrix SSL Error 8: Initialization failed. Error number: 183

I want to report back that I got everything working. This is what it took. The Mac not only had Citrix Receiver on it, but it also had Citrix ICA Client which is really old. It appears that the administrators of the Citrix Server had made some updates with which Citrix ICA Client was not compatible. So I got Receiver uninstalled, ICA Client uninstalled, and then installed Citrix Workspace and everything works now. Hopefully if anyone else is having the same problem, they can find the solution here. Shout out to Tesserax for his or her help.

Hi Tesserax. Thank you for taking the time to reply. Here are the steps that I have tried so far. I downloaded the most recent version of Receiver and then deleted the version of Citrix Receiver that was on the Mac using the un-installer that is on the disk image with the installer. I then re-installed Receiver. I did not download Workspace. I can try that. The user I am trying to help goes to a website, clicks a link that downloads a .ica file and then she clicks that .ica file and it opens the Citrix session in her browser. We have tried both Chrome and Safari and gotten the same result. I went to the Citrix support site and this forum post seems to be the closest to relevant:

I opened a ticket with Citrix but have not heard back yet. Really just trying every avenue.

Thank you again for helping out.
