Hi All,
We have a strange issue which has occurred on our Gateway servers.
We have 2 servers (in separate data centers) which are configured in a cluster, I'll call them G1 and G2 for simplicity.
Recently, G1 was patched for a security flaw and the TLS1.0 protocol was still disabled. Since then, only some of the connections are failing. Each of the connections show this info
Unable to connect: This data source cannot connect to any gateway instances of the cluster. Please find more details below about specific errors for each gateway instance.Hide details

GATEWAY: | We reached the data gateway, but the gateway can't access the on-premises data source. |
This definitely not related to credentials - because we separately set up the same connection on G2 (which has not been patched as yet ...) and those connections now work fine !
I can run tracert from G1 to the hostname of server which the Gateway says it can't reach.
It is bizarre as only some of the connections are failing, and the ones that are
How do I check what TLS version on-premises gateway is using (I'm assuming at least TLS1.1 , but probably TLS1.2 ?) or how can I trace what is blocking the Gateway from connecting to the host ? .
Our network and OS support folks are adamant it is an "application" issue, but I'm not convinced !
Anyone else seen similar issues once TLS1.0 is disabled ?
