[raphael10-collab]

In /etc/prosody/prosody.cfg.lua I've set this VirtualHost:

VirtualHost "uxpug2bqoujpbjgtwogesqvixybtknziv7ieu3jfhuyxs5b4afjq.b32.i2p";
    ssl = {
        key = "/etc/prosody/certs/uxpug2bqoujpbjgtwogesqvixybtknziv7ieu3jfhuyxs5b4afjq.b32.i2p.key";
        certificate = "/etc/prosody/certs/uxpug2bqoujpbjgtwogesqvixybtknziv7ieu3jfhuyxs5b4afjq.b32.i2p.crt";
    }

    https_certificate = "/etc/prosody/certs/uxpug2bqoujpbjgtwogesqvixybtknziv7ieu3jfhuyxs5b4afjq.b32.i2p.crt";

    modules_enabled = { "presence_identity" }

    asap_accepted_issuers = { "jitsi", "GD" }
    asap_accepted_audiences = { "jitsi", "GD" }

    authentication = "token"

I get the following errors:
