Cannot install and use Acrobat Export with Acrobat reader -- absolutely cannot log in

[jeffl@WKM]

I've just wasted a day of my life on the monumental task of setting up a user with Acrobat Reader and the Acrobat Export add-in.  I was told that the Acrobat Export was successfully acquired.  But no way, no how can I sign in from Acrobat Reader and use it.  When I try to sign in, I always get this 100% useless copout error message:

If I try to log in at https://auth.services.adobe.com/, I get this:

Another computer with Windows 10 and Microsoft Edge (updated to the minute on both machines) can log into the web site with no problem at all with the same credentials.  (Yes, I'm logged out of it when I try signing in with the problem machine.)  I've researched this issue on the web and the only useful information I could find was that the TLS version of your browser has to be 1.2 -- which it is on both machines.

I'm not insane enough to keep "trying again later" expecting different results.  I'd bet anything that it's going to take some under the hood support to enable me to successfully log in -- that the error message will persist forever if none is forthcoming.  Is there a known solution for this problem with this combination of products?

Hi jeffl@WKM 

Hope you are doing well and thanks for reaching out.

Would you mind sharing the version of the Acrobat Reader and the OS you are using? To check the version please refer to the help page https://helpx.adobe.com/acrobat/kb/identify-product-version.html

Also, please check your connection with Adobe servers and try to reset the host files manually as described in the help page https://helpx.adobe.com/x-productkb/policy-pricing/activation-network-issues.html Also check out the page https://helpx.adobe.com/download-install/kb/common-network-connectivity-issues.html and see if that works.

You may also try to create a new test user profile with full admin rights in Win or enable the root account in MAC and try using the application there and see if that helps.

Regards
Amal

As mentioned, everything is up to the minute.

None of those tips did anything, but one of them gave me a clue that enabled me to find the answer.  I was able to access the Adobe activation server, but the screen displayed THIS first:

On the machine that could log in, the logo came up instantly.  The machines were on different DNS servers, so I made the ones on the problem machine the same as the ones on the working machine -- Compuserve's 8.8.8.8 and 8.8.8.4 combo.  It worked.  I strongly suggest that you update that activation issues page to include trying this.   

p.s. PLEASE get rid of that idiotic "try again later" message.
