Check nginx logs for errors.

@damencho thank you for respond.
I check it are say this

“/usr/share/jitsi-meet/static/base.html” failed (2: No such file or directory)
“/usr/share/jitsi-meet/static/title.html” failed (2: No such file or directory),

But these 2 files both of them are inside /usr/share/jitsi-meet/ not inside /usr/share/jitsi-meet/static/
I are do something wrong?

I see this one too

SSL_do_handshake() failed (SSL: error:141CF06C:SSL routines:tls_parse_ctos_key_share:bad key share) while SSL handshaking,
