Hello...i'm having an issue after upgrading our connection and security servers from 7.4 to 7.9. We have thin clients running Horizon Clients. When they first start up, we get an http error 503. After about 10 seconds or so, they can connect. This just started after upgrading our connection and security servers. I'm not sure exactly where to go to even troubleshoot this issue. Attached below is a picture of the error I'm getting.
Thanks,
