I've just checked with our developers on the issue and they've let me know that our servers are up and running and there were no recent downtimes or other issues on our servers within at least the last 7 days.
Could you please let us know if you have any antivirus/firewall software installed on your Viewer machine?
No Changes to AV or firewall last 7 days, everything was working yesterday, but today, unable to connect via Internet ID. I have connected fine to in house computers, using IP Address, but not able to access any remote PC's, a couple of external user have also reported this as a fault. Have set them up with VPN connections, and changed them to IP Connect.
This is not a device issue. I have the same issue as others here and I’ve temporarily switched to an alternative app on two computers and it's working without any issues. Direct connection is also working.
I thought it may be an ISP level block on your ID servers, but I get exactly the same issue with or without a VPN.
