Disconnected from the server

[jennylvantiem]

Hi .
After installing Warp and changing the server's IP to Cloudflare's IP. After a few seconds, my connection with the server is lost and I can't do anything. I have to rebuild the server.
I have easily installed and used it on several other servers. But today I encountered this problem.

Did you install any other special proxy services or applications before installation??

Me too, lost connection with the server after running the script. After input of password, it shows that"access denied".

I didn't configure firewall after getting my server.
