DPS Error when trying to download "Unknown. The request was aborted. Could not create SSL/TLS secure

Good morning all,

I have a customer whereby the above message has just started - was ok last week....

"Unknown. The request was aborted. Could not create SSL/TLS secure channel" when they click on OK to communicate out to HMRC

We've rebooted the servers in the first instance and I've arranged to upgrade them to Scheduler 2.21.10 this afternoon but just wanting to check if the above could be related to anything else?

Regards

Claire

Hi Claire

It looks like it is probably due to their Operating System.

Please refer to the KB 3531498 as coped below.

KB3531498

RTI and MTD submissions are no longer accepted by HMRC if using old operating systems.

Since this update below was released, we have had notification from HMRC:

We made a change to remove support for some older more vulnerable cipher suites. As previously mentioned in May, this would be temporarily reverted for a few weeks, this time has now passed and support for the older more vulnerable cipher suites has been removed.

Advance notice of the Cipher changes were sent out in Sept 2023, Jan 2024 and May 2024

Pegasus has received confirmation from HMRC, that HMRC are no longer accepting RTI and/or MTD Submissions from any of the following operating systems:

• Windows 7
• Windows 8/8.1
• Server 2008
• Server 2012
• Server 2012r2

This change took effect from 9th May 2024.

Steps to Take:
• Update your computer’s operating system.
• Use a networked device with a compatible operating system for submissions.
• Install our software on a device running a supported operating system.

Hi Len,

Many thanks, yes their server is still 2012 however we put a workaround onto a Windows 10 PC for their RTI which is not working either - looks like I'll have to take it to the next level and put scheduler/sql onto the PC but i'll try the update first of scheduler just to be sure to be sure....

Hi Len,

I am also getting this message "Unknown. The request was aborted: Could not create SSL/TLS secure channel" but the server is :-

Microsoft Corporation, Microsoft Windows Server 2022 Standard (10.0.20348) (en-US)

I have updated the Scheduler to 2.21.10(1)

But still an issue.

Any ideas?

Kind regards

Conleth
