When using TLS 1.2 with Single Sign-on (SSO), users running Alliance 14.0.0.24 may encounter the following error that the “Astea Application address is not valid.” If this happens, it may be because the 64-bit Publisher with TLS 1.2 support has not been installed on the Publisher server(s). Please check the publisher server to ensure that publisher was installed using Alliance Publisher 14.0.0.24 Full (x64).exe.
We recently had a client that utilizes TLS 1.2 and SSO and received this error after re-installing publisher. This was because the server only supported TLS 1.2; however, the 32-bit version of Publisher was installed without TLS 1.2 support. The client browser could not establish a connection with the server to verify the Alliance URL and as a result, the following error was displayed:
To resolve the issue, the client uninstalled Publisher from the publisher servers and re-installed using the 64-bit version with added TLS 1.2/SSO support.
