[MayankMalhotra]

Hi there!

I have tried many times but it wont let me signin to Creative Cloud Add-in which I have just installed in Powerpoint (MS 365). It shows following message.

Any help/guidance would be appreciated 
Thank You

try signing in using your cc desktop app.

if you see the same message, confirm that you can connect to the secure adobe servers by reading, http://helpx.adobe.com/x-productkb/policy-pricing/activation-network-issues.html do you see both logos?

if you can and still see a connection error, white list the adobe network endpoints, https://helpx.adobe.com/enterprise/kb/network-endpoints.html

Thank you fo your reply!

The actual issue in my case was AVG Tuneup Software who forced some background services sleep!

Hi Kglad

I am having this problem again.

As you stated

I can see both logos on http://helpx.adobe.com/x-productkb/policy-pricing/activation-network-issues.html

But I am still getting error!

Newbie here. May you please tell how to white list the adobe network endpoints?

Thank You!

google your router and/or firewall for how to add to your white list.

but, if you solved the problem before by doing something with other software (eg, avg tuneup), white listing adobe endpoints won't help.

why did the problem return?  ie, check av, antimalware, cleaner, tuneup, defragger software on your computer that might cause the problem.  then you need to stop those programs or, at least, stop them from interfering with adobe processes.
