Help please

I am with the “Beep” machine (I am doing an ethical hacking course) I have the machine active, the vpn active and I have already carried out the tests to verify that everything is in order. The problem that I get when doing a “whatweb” I get that error “ERROR Opening: - SSL_connect returned 1 errno=0 state=error: dh key too small” When I try to access it from url I get The following error appears in the browser “ERR_SSL_VERSION_OR_CIPHER_MISMATCH” I looked at many internet pages trying to find the solution, but I did not get anything…
Would someone be so kind to help me please?
