I have set up a server on Doprax to run a v2ray-fork from github. I connected my cloudflare worker to it for host and SNI. I made a Vmess server and it was working just fine for about 20 days. It suddenly stopped working and the message on V2ray (windows 11) is "the underlying connection was closed: An unexpected error occurred on a send".
The Doprax server is still running. I have reset it several times and checked for the success message "If you see this page, the nginx web server is successfully installed and working." The worker is also running; I checked the accessibility of server through worker, the same success message as it appeared through direct access. I have already changed several IP addresses to prevent ip address blockage. Not working.
