Hello. Nope, this error says that port 8441 is busy. You either have another webserver on this port or you have another Blynk server running.
If your server is on linux try …
netstat -tulpn | grep 8441
… to see if there is a process using this port already.
Thanks all yes a process on 8441 had killed it fine nw

Please stop creating new topics for same server issue… I have merged them all here.
PS, properly copy/pasting formatted logs and debug info is much prefered to screenshots with little tiny text that no one can or will read 
@aruneshdutta this error usually means that Let’s Encrypt can’t reach your host at 80 port. Did you make port forwarding from 80 to 8080?
