Communication failure between Opera 3 and HMRC

Hi everyone, I've got a situation where an existing Opera user is getting a message when they are accessing the MTD Centre.

'A communication failure between Opera 3 and HMRC has occurred (S500). There are several reasons why this can happen.'

We've re-loaded, tried a different PC - same message, and even spoken with HMRC to check the gateway isn't down.

I've logged a ticket with Support but time is running out. They've sent me instructions about checking Scheduler on the Server (2019 btw) and this hasn't worked - its not the same error tbh.

Support have also asked if there are any firewall rules etc, I've checked that port 443 is open on their firewall and their AV product hasn't changed in 12+months.

I've logged in on the Server rather than the user's PC and it comes up with the same message. If I log in as a different user then I get the Authorisation needs to be completed message instead, but this also fails with a different response from HMRC saying 'You cannot access the service from this page'.

Their HMRC account is valid/working as I've logged into it from the Server (as administrator). The only thing that's happened recently is they've had their Payroll Upgrade (2.99.03).

Any help would be appreciated as I'm running out of ideas - and time!

Have you tried the debug it often gives a more detailed reason:

You can also do the following to find more specific information other than generic code:

1. Create a file called DebugMTD.txt
2. Place that file in ProgramData>Pegasus>Scheduler Server
3. Restart the Scheduler Service.
4. Run the MTD Process that generates the error.
5. This should create log files in ProgramData>Pegasus>Scheduler Server - if you can copy those on to the call.
6. Remove the DebugMTD.txt from ProgramData>Pegasus>Scheduler Server
7. Restart the Scheduler Service.

Thanks for this, I'll see what occurs with the .txt file as that could be helpful!

Hi Susan, just a thought - have you checked that .net framework 3.5 is still enabled on the server/device where Pegasus Scheduler is installed and running from?

Also, what version is the Pegasus Scheduler - has it been updated to 2.21.10?

Claire

Hi Claire

Scheduler is 2.21.10 - I will ask their IT to check .NET - thank you!

We have had several instances where we have had to install SQL and Scheduler locally as the server is/was running 2012

Everything works fine but on a later MTD it is unable to communicate with HMRC as per above.

When we checked in the registry the keys were pointing back to the server, which obviously wasn't going to work. When we changed them back to the local machine it was fine.

Hi, Carolyn,

Not sure if this is your problem, but upgrading Opera 3 resets the Scheduler Registry entries back to pointing to the server.

We have had to introduce a new task to our Payroll Upgrade process, to reset the Scheduler Registry entries where the local install has been done.

Kind regards

Steve

That's great, thanks Steve

Hi Susan

So I had a similar issue yesterday(S500 comms error) and for speed, I setup scheduler on local machine. This allowed everything to authorise and work for MTD.

To get to the decision to run locally, I ran the opera3.azurewebsotes.net directly on IE on the Opera server and I could see it was being blocked - MTDCommsTest.exe confirmed it wasn't able to reach this website on the server.

Installing scheduler t locally got around the deadline.

Still waiting for IT to remove whatever is blocking on the server (appears to be remote certification?) but the local machine is at least less restricted.

Thanks Tony

I tried installing locally but this didn't work, reading through everything I am convinced it's something blocking on their system. Their IT were really helpful yesterday but they have yet to respond to my request regarding your suggestion to unblock opera3.azurewebsites.net (nor the suggestions made by Pegasus support this morning) so I am going to chase this up tomorrow. Once I know what has caused this I'll update everyone!

Hi Carolyn, I installed it locally (and as per Steve, tried the registry settings etc). I'm currently awaiting their IT to confirm about whether a specific site has been blocked as per TonyC's suggestion). Will update when I know more!
