Connecting to onpremise crm 365

Posted on by NickGravaSP2 2
Hi everyone! I have onpremise 365 crm dynamics 9.1.0032 version, working on http protocol. I change binding in IIS to https, change protocol in DeployManager to https, change SiteUrl key in RegEdit to https. UI works good, but i have some errors when i try to connect to crm from asp net application (not asp net core). Sometimes i have error: Metadata containes the reference that cannot be resolved! And url address to metadata is HTTP protocol. The error is floating and occurs only when I receive the IOrganizationService object using the POST method. When connecting, I specify useSSL = true. Tell me please what the problem might be?

    Check if there are any references to HTTP URLs in the metadata. Sometimes, the metadata might contain hardcoded HTTP URLs that need to be updated to HTTPS.

    Thnx for your answer. 
    But can you tell me where I can check URLs to metadata? 
    To connect to CRM I use this code:
    ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
var crmServiceClient = new CrmServiceClient(credentials, hostname, "443", "nameOfMyOrg", false, true);
if (crmServiceClient != null) && string.IsNullOrEmpty(crmServiceClient.LastCrmError))
  return crmServiceClient;
     
    So URL in code must be with HTTPS protocol, but it sometimes not...(
