Unable to update machines remotely

Hi!

We have problems updating our machines remotely. We are not using IQANconnect.

We have three controllers in the machine: MD4-10, MC42 and MC43. After sending a new project to the machines and during the reboot this is displayed on the MD4:

And there it stops. After a while we power cycle the MD4 and it boots up normally. However, the MD4 has no contact with the other controllers and, if I am remembering correctly, we have a "System mismatch". Rolling back to the previous version restores everything. Trying to update the machine with the new project results in the same issue as mentioned before. And we are in a loop...

Connecting directly to the MD4 with an ethernet cable works flawlessly so I am suspecting a communication issue. Connecting directly to the MD4 means we have to travel across half the country for an hours work though...

Our communication solution has worked great in the past. I've talked to the IT department and they say that nothing has changed regarding our communication solution so I am reaching out to you:

What is going on behind the scenes at the moment the picture was taken?

Do you have any suggestions on how to solve the issue?

At the moment we hesitate to update our machines because of this. To be honest, just thinking about an update makes me sweat :)

I will be happy to provide you with any information you may need as this is very urgent.

Thank you in advance!

Kind regards,

Christopher Fridstaden
