Address the DDE Server Connection Error
Fix the underlying Dynamic Data Exchange (DDE) server communication issue which frequently triggers the sign-in loop in Acrobat.
In many cases, the repeated authentication prompt is tangled with an error where Acrobat fails to connect to a DDE server. Temporarily modifying the security startup settings can bypass this block.
Launch Adobe Acrobat Pro DC. Go to the top menu, click on Edit, and select Preferences.
In the Preferences window, select the 'Security (Enhanced)' category from the left pane.
Uncheck the box next to 'Enable Protected Mode at startup'. Click OK to save the changes.
Close Adobe Acrobat completely, then double-click your PDF file again to see if the sign-in prompt is bypassed.

Frequently Asked Questions
Why does Acrobat Pro DC keep asking me to sign in?
This is often caused by a communication error with the DDE server, corrupted login tokens in the cache, or outdated software conflicting with Adobe's authentication servers.
Will reinstalling Adobe Acrobat fix the sign-in loop?
Reinstalling can help if the core installation files are severely corrupted. However, repairing the installation via the Help menu or resetting the Adobe preferences is usually faster and should be attempted first.
Can I view my PDFs offline without signing into Acrobat?
Adobe Acrobat Pro DC requires periodic sign-ins to verify your active subscription status. If offline for over 30 days, it will prompt for a sign-in. For pure offline viewing without an account, a lightweight PDF reader like WPS Office is a better alternative.
How do I fix the 'failed to connect to a DDE server' error?
You can resolve this error by updating your Acrobat software to the latest patch or temporarily disabling 'Protected Mode at startup' under the Security (Enhanced) Preferences tab.
