Unable to connect to the Adobe update server. Error 105

As described in this ticket, updates for Adobe Acrobat and Reader no longer work on various Macs.

https://community.adobe.com/t5/download-install-discussions/unable-to-connect-to-the-adobe-update-server-error-105/m-p/15516249

I won't go into the details here, as they can all be found in the linked ticket.

Unfortunately, the last ticket was simply closed by the Adobe employee, even though there was no solution. I find this approach more than questionable, considering that we are all paying customers. If something like this happens again in this ticket, I will contact Adobe management directly.

@Anshul_Nautiyal  Miracles do happen after all. As of today, updates are working again on ALL computers. So, as suspected, it wasn't a problem on the clients, but Adobe solved the problem on the servers in general. I would have liked them to have taken the problem seriously earlier, but the main thing is that it's solved now.

    Dear @Anshul_Nautiyal,

     

    Please excuse me for being a little blunt here, but my/our patience is slowly running out. If you read the original ticket carefully, you will find that all your questions have been answered.

    • Yes, it only affects Adobe Acrobat and Reader.
    • All other applications can be updated.

    The troubleshooting steps are not working! This is also described in the original ticket.
    As you can see, several users have completely reinstalled their computers and reinstalled Acrobat. The error still occurs. Once again, this is not a problem on the clients, but on your side on the servers. We pay Adobe a six-figure sum every year. I would now ask you to take this issue seriously and contact Second Level Support as soon as possible. If we suffer any damage due to missing security updates, e.g. a successful hacker attack that exploits a security vulnerability, we will hold Adobe responsible!
