I have a room having Poly C60, TC10 and G62. 

Issue just happen on C60, intermittently, in most of the time it fails. There is a routine reboot on devices in the morning. Sometimes error 5003 shows the disconnection from Zoom after reboot, and unable to connect then. Rebooting not fixing it. 

When see error 100006000,  we use the activation code, it goes to Error 5003.

      Hello ​@Kayan Chan 

      Error 5003 could be a few different issues. You can find out more about the error here: https://support.zoom.com/hc/en/article?id=zm_kb&sysparm_article=KB0070334

      I would advise verifying the network firewall and proxy server settings are followed per this article: https://support.zoom.com/hc/en/article?id=zm_kb&sysparm_article=KB0060548

      Lastly, verify the device itself is on the latest firmware and there is no anti-virus blocking any connection to Zoom.

      I hope this helps and if this answers your question please make sure to mark this as a solution.

       

      Thank you,

      Jake
