привет, я пытаюсь зарегистрировать свой сервер OP C -UA на локальном (пока) локальном сервере обнаружения. Поэтому, когда я запускаю свой сервер с registerServerMethod
, установленным на lds, я получаю эту ошибку:
RegisterServer to the LDS has failed during secure connection => please check that you server certificate is trusted by the LDS. err: The connection has been rejected by server,
Please check that client certificate is trusted by server.
Err = (connect EINVAL 0.0.14.186:4840 - Local (0.0.0.0:0))
, поэтому, когда я проверяю отклоненную папку LDS в (opt / opcfoundation / ualds / pki / rejected / certs ) сертификаты туда не помещались.
Я пробовал несколько разных сертификатов, я привязал копию сертификата к доверенной папке, но пока ничего не работает. Я делаю что-то не так с LDS ore Что-то не так с моим серверным кодом:
