Issue
On Tuesday the 14th of July, Google released Chrome version 84.0.4147.89. In this update Google have deprecated support for TLS versions 1.0 and 1.1. This has impacted any Windows 7 machines that are running this version of Chrome (84.0.4147.89) or later as Windows 7 does not have TLS 1.2 enabled by default.
As per the Docman 10 Warranted Environment Specification (https://help.docman.com/knowledge-base/warranted-environment-specification-wes) all PCs used to access Docman 10 should be using TLS 1.2.
In order to connect to the Docman Desktop Services via SignalR the local PC needs to connect to https://dts.docman10.com. If the local PC does not have TLS 1.2 enabled it will attempt to use TLS 1.1, as this is no longer supported by Google Chrome an error will occur and the desktop app icon in Docman 10 will turn yellow. This will indicate to the user there is a problem and the Desktop App cannot be used.
Impact
Without the Desktop App functioning correctly the local PC will not be able to utilise the API with the practices Clinical System which prevents the use of Single Sign On, filing to the Clinical System and opening documents from the Clinical system. This issue will also prevent scanning documents into Docman 10.
Workaround
Practices are advised to use Internet Explorer which will still function correctly.
Solution
In order to resolve this issue two changes will need to be made on the Client PCs that is running Windows 7.
The following keys will need to be set to the following values:
Location: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Client
Change DWORD name: DisabledByDefault to DWORD value: 0
Location: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Server
Change DWORD name: DisabledByDefault DWORD value: 0
Following this change, the PC will need to be rebooted in order for the change to take effect.
Guidance for Users
In order to resolve this issue we recommend contacting your Local IT provider and requesting the above fix to be implemented on the affected PCs at your practice.
Please do not contact the Docman Service Desk for this fix to be applied as they are not authorised to make this change.
