Thank you! Fixed it 

HOW DID YOY FIX IT? Pls explain with more ifo? id really appreciate it

I don't know if you still need it, but for someone else who has the same problem:
1) open a notepad as Administrator
2) in notepad go to file, open and open the host file (C:\Windows\System32\drivers\etc\hosts)
(for me, when i used a notepad to open the file I couldnt see the hosts, if you have the same thing just open the file explorer and there open the file with hosts in the notepad (also make sure you can see the hidden files), after this run a notepad as Administrator and your host file will be there)
3) delete everything that related to adobe (for example,
0.0.000 adobe.com or
0.0.000. adobe.io)
(i deleted like 15 lines)
4) save file and restart the adobe
P. S. big thanks to Янн32783576eo4h, he gave me a good hint how to fixit. I spent 2 hours just trying to understand what was going on and why the subscription was paid but the programm couldnt verified it and had some connection error.

hey, can you do a tutorial? i am facing the exactly same problem, although i have no clue how you solved it

How are you installing the software? Editing a host file is not authentic.

I have found a solution. For some reason, data about the adobe verification server was entered in the host file. I deleted them and everything worked.

All of the errors you are indicating are server dropped connection errors. There is nothing wrong on the Adobe server side as noted at status.adobe.com - so we're left troubleshooting your internet connection. What country are you located in? Are you using a VPN?
