Creative cloud not opening (Cannot connect to adobe servers please check your firewall settings)

[Rick5C9E]

Yesterday everything seemd completely fine but today I can open cloud and I also can't open apps by their own. When i open apps by their own there keeps this thing popping on my screen where it asks me to log in but it goes away before I can even click on it and then comes back again and again. Hope someone can help me out cause i really need it to work for college

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
