SSL certificate exchange issue between App server & Loquendo
server.

Solution

Please try the following steps to fix the issue:

- Apache Tomcat Application server on a first Linux CentOS 6 32-bit
- Updated it to run TLS/SSL per Avaya instructions (as they are per Windows systems, not all commands works at the first shot)
- Enabled also TLS/SSL
- Tested that a simple grammar “digits.xml” can be viewed by any browser both on port 8080 and secure port 8443
- Installed Loquendo Speech Server on a second CentoOS 6 32-bit machine
- Installed an MRCP client on a third machine
- Tested that the above grammar could be passed to Loquendo via standard port 8080 but failing via secure port 8443

Then:
- Updated the Loquendo configuration parameter httpSslVerifyPeer to “disable (0)” instead of the default “enable (1)” On Management Console paths are
Loquendo -> Local (127.0.0.1) -> Configuration -> Advanced -> ROCacher -> http -> httpSslVerifyPeer = disable (0)
and
Loquendo -> Local (127.0.0.1) -> Configuration -> Advanced -> MRCPv1Serverr -> http -> httpSslVerifyPeer = disable (0)
- Re-starter Loquendo from Loquendo -> Local (127.0.0.1) -> Administration
Tested again the above grammar through the secure port 8443 with

 SUCCESS!!!

So, please apply in your installation the updates above and try again (from you InfoCollector I see they are enabled).
