You may find it necessary to set these App Pools (K2_net4) to use a later version of. NET version associated with App Pools linked to the K2 sites. (provider: TCP Provider, error: 0 - An existing connection was forcibly closed by the remote host.), it might mean that one of the app pools used for a K2 site is still set to use an earlier version of the. If you see errors like Initialization failed before PreInit: Membership could not be verified: A connection was successfully established with the server, but then an error occurred during the pre-login handshake.NET apps on the K2 server, including K2, configure all settings as listed in the minimum requirements section above, and then also add or edit the following keys in your K2 server's registry: Registry Path To implement the maximum protection for all. To implement the minimum requirement, add or edit the following keys in your K2 server's registry: Registry Path You should back up the registry before making any changes, and you should be familiar with editing the registry before adding or modifying these keys. Be sure to test these changes in a non-production environment after making them so that you don't unexpectedly break other systems that may not support TLS 1.2.Įditing the registry incorrectly can cause system instability or crashes. NET Framework 3.5 or earlier did not originally provide support of. NET applications on the server, not just K2. NET and system-wide settings and affect all. Maximum Protection: Force the entire server to only allow TLS 1.2 connections so that incoming and outgoing connections use this higher level of security.Minimum Requirement: Make sure that the K2 server can communicate with other services that only allow TLS 1.2.To avoid these issues you have two options: Below is an example of an error that may occur when TLS 1.2 is not configured correctly: If the server on which K2 is installed is not correctly configured for TLS 1.2, errors may occur. Net 4.6 runtime, which fully supports TLS 1.2, for both server (inbound) and client (outbound) connections. 2.1 Secure Data Network System 2.2 Secure Network Programming 2.3 SSL 1.0, 2.0, and 3.0 2.4 TLS 1.0 2.5 TLS 1.1 2.6 TLS 1.2 2.7 TLS 1.3. NET Framework (Microsoft) and does not specify a TLS or SSL version.

K2 follows the Transport Layer Security (TLS) best practices with the. With the PCI move to TLS 1.2, when a K2 solution is integrated with these providers and the system in which K2 resides is NOT configured for TLS 1.2, possible communication errors may occur. K2 integrates with many 3rd-party providers such as Microsoft SharePoint, DocuSign, and SalesForce. With the PCI Security Standards Council's move to Transport Layer Security (TLS) 1.2 on the 30th of June, 2018, various 3rd-party providers are disabling the use of older TLS and SSL protocol versions in their products.
