Hi,
On June 1, 2021 we started to have problems connecting to CRM from our custom applications. The issue started to occur in all environments at the same time. Nothing was changed from our side
For the connection we use
CrmServiceClient passing as a parameter connection string
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12; _crmServiceClient = new CrmServiceClient(ConfigurationManager.ConnectionStrings["Crm"].ConnectionString); if (!_crmServiceClient.IsReady) { throw new CrmConnectivityException("Can't connect to Crm", _crmServiceClient.LastCrmException); }
connection string
Url=test.crm3.dynamics.com; Username=test; Password=test; authtype=Office365
looks like microsoft did some changes to the online platform.
This is production issue, so, any help is appreciated.
Thanks,
Maksym
