Before using the FIX FUTEX option, did you see the error "futex facility returned an unexpected error"?
Did you change anything manually? Or did you had an error message during the initial installation? Please check the /usr/local/sbin/ path to see if ocserv is located there

I didn't modify anything, and I didn't pay attention to whether I received an error message during the installation process, but I found that I couldn't connect after the installation was completed. When I replaced the system with Ubuntu20.04 and installed it again, the connection was successful.
