Acrobat Reader DC stopped working, Error 206 on Mac No Firewall

All of a sudden, my Adobe Acrobat Reader DC cannot open any pdf. I tried help - look for updates, but got error 206, can't connect to server. My computer can access the internet. The Firewall is off. 

 

The only help I've found on this topic applies to PC. My firewall is set to off, so it's not that. 

 

I'm not in the same galaxy as IT, so if you have any suggestions, please adapt it to the most basic understanding. 

 

Mac OS Mojave v 10.14.6

Hi there

 

Hope you are doing well and sorry for the trouble. As described you are getting the error 206 and the error message 'Unable to connect to internet'

 

Do you have the TrendMicro security software installed on your system? If yes, please check the help page https://helpx.adobe.com/acrobat/kb/cant-verify-your-subscription-status.html

 

Also please check your connection to Adobe servers and try resetting the host files manually as described in the help page https://helpx.adobe.com/x-productkb/policy-pricing/activation-network-issues.html

 

Let us know if you experience any trouble and need more help.

 

Regards

Amal

Hi Amal:

 

I have never heard of TrendMicro Security Software. I assume I don't have it. 

 

I followed the second link. I can connect to the Adobe server, because I got both the Adobe icons. However, the next suggestion was to activate my app by signing in. I am using a Mac, and when I open Adobe Acrobat, it does not ask me to sign in. It just opens, just like Word or Excel. 

 

The following suggestion was 

"Start a web browser and open one of the following links, depending on the version of your product:

I have Acrobat Reader DC 2021.005.20058. Which one of these am I supposed to use?

Since that did not work, I uninstalled Adobe Acrobat DC and then reinstalled it. When I click on the installer, I get the error message "no such file or directory." I started a new post with this problem. 

 

I urgently need to be able to read pdf, related to our business. I need help ASAP solving this problem.
