From ARD Studio 188.8.131.52, unable to login to ALM it shows " HTTP 0: Unreachable. Please check your URL ".
This was working one week before.
This issue most probably happened due to the update done to WinSCP software in ARD machine which uses the OpenSSL framework that is used by ARD as well and modified the supported TLS versions.
The TLS version supported by ARD 184.108.40.206 is TLS 1.1. If the WinSCP update changed the OpenSSL supported TLS version that doesn't include TLS 1.1 then this issue would occur.
Release : 220.127.116.11
Component : GT HP ALM Integration
We can check the TLS supported versions of WinSCP from below instructions in below link and update the range to include TLS 1.1.
Note: Such connectivity issue involving HTTPS connection may arise due to changes done to OpenSSL framework by updates done to any other software as well. Hence, it is recommended to keep track of the software upgrades done on ARD machines for easy debugging of the issues.
