error start on 2022-04-01, before it works well. i think problem is TLS 1.1, TLS 1.0 (Older version) disable in office 365 at 2022-04-01.
and can not enabled on 2011 On-Premise (if exist enableing tls 1.2, teach me)
--------------------------------
i found this : Download Dynamics 365 Update 2.2 for TLS 1.2 supported clients from Official Microsoft Download Center
is can support to Dynamics Crm 2011 ?
