We finally got our screens all showing online however over the weekend they have gone offline again. Our service provider who manages our Firewall and Filtering states they haven't changed anything so the problem isn't on their end.
Has anyone had it where screens just all appear offline suddenly? All 12 screens lost connection to myViewBoard Manager within a 48 hour period.

Hi Noel, could you please try to open the manager app on the screen and let us know what message showed in the manager app?
And please let us know your entity name, we will check what happened, thank you. -
@peja-cw-chang Hi,
The manager app on the screen works as expected and states it's paired. Our service provider thinks the IP address has changed that was being used last week (they have been advised multiple times to whitelist AWS and not an IP address but re reluctant).
Our Entity name is The Burton Borough School

@noelmm Hi,
All devices shows offline in Manager web means we can't establish the mqtt connection between IFP & Manager web, it looks like a network connection issue.We would suggest whitelist "AWS domain" instead of its "IP address",
this is because AWS used a long list of dynamic IP address instead of fixed ones. If they still want to use IP address, they may need to whitelist hundreds of IP address, that would not be an efficient way, the list might also be changed in the future.let me know if you have any further questions, thank you

Hi,
Our service provider cannot use wildcards in their firewall and will not whitelist "AWS" as a domain as they say it is not a secure way of working.
Are you able to provide a full list of IP addresses used (I know there will be a lot) and I can have each one of them whitelisted individually?
-
I have also been asked for clarification on what needs whitelisting. Our provider has asked, Is it the root AmazonAWS.com domain or perhaps ‘something.something.amazonaws.com’?
Thanks

Are you able to advise?

@noelmm
please see my responses below:- Is it the root AmazonAWS.com domain or perhaps ‘something.something.amazonaws.com’?
- Yes, please whitelist *.amazonaws.com, allow "something.something.amazonaws.com" ...etc
- Are you able to provide a full list of IP addresses used
