Vidyo is tracking an issue with OCSP authentication via GoDaddy certificates in the use case of Neo for WebRTC using 4.2.0.x version and the FireFox browser only.
The symptoms are inability to connect to the page on Neo for WebRTC 4.2.0 and FireFox if the certificate authority is GoDaddy.
Vidyo is working with the provider in order to remediate the OCSP GoDaddy server responsiveness issue.
This phenomena is not currently affecting VidyoCloud customers using Neo for WebRTC.
