Sid D 4 Posted January 27, 2023 Hi, I am getting the following error for TIdServerIOHandlerSSLOpenSSL when starting the Windows Service. Running the app as stand-alone server does not throw the error. The error is thrown only when starting this Windows Service. Could not load root certificate. error:0B084002:x509 certificate routines:X509_load_cert_crl_file:system lib The Delphi version used is Delphi 10.1 update 1 and Indy version is 10.6.2.5341. The root file is in pem format. What can be the reason here? Thanks Sid Share this post Link to post
