java.security.cert.CertPathBuilderException: No such signature algorithm.
It appears that UCCX doesn't support RSASSA-PSS which Microsoft uses on the root and issuing ca. Are there any workarounds for this?
Did you find a solution to this? I'm having the same problem on callmanager and presence 10.5
Had to reconfigure our CA to use SHA256 ciphers and reissue the certificates
