Zoom Room Error Code 5

Our room was under construction for about 6 months and just came back online. When it came back on we keep getting the error code in the image. 

We have a Zoom room connected to a Crestron brain. I saw that error code 5 means a mismatch between the Crestron and Zoom. I changed my Zoom room to mountain time, and the engineer changed the Crestron unit to the correct time, but we're still getting this error.

I'm also trying to update the Crestron firmware through Zoom but it's getting stuck and timing out.

If the time is correct on the Crestron, could a network switch be getting in the way?

Any ideas? 

Thanks!
