Hey Jeff,
we have the identical error starting after updating to PT 2021 and getting more until today. RN it happens about every 2 minutes. If you have any helpful infos please let me know!
Thank you very much!

There are many things that can cause a network error, so each issue/system should be treated independently. It's not a single bug.

• Older MTMs (with M10 or M40 written between the softkeys) have to be connected to Ethernet port 1 on the back as port 2 has known hardware issues.How to change ports
• Network hardware, from the cables, switches, passthrough connector in the S6, and settings in a non-Avid supplied switch/router,
• EUCON only supports EUCON, Dolby Metadata and Satellite on its network, no Audio over Ethernet, Web or Network Storage.
• Check other network ports on the Workstation, make sure that they are not in the same subnet. IE. the first 3 numbers in the IP address are not the same x.x.x.0
• If the Workstation CPU/memory/network is overloaded, it will cause these issues
• If the PT session is overloading PT it will cause these issues.
• PT/EUCON 21.10 onwards removes a lot of the PT overloading/EUCON performance issues.

Hey Eddie,
Thanks for your answer!
The thing is, we had this setup running perfectly smooth since 2016. (all the usual tricks and practices applied) Only started to behave like this mid 2021. We've trying to solve it with our Audio-IT specialist and had some analyzing running which showed us a spie in the network every time before the S6 lost connection. No idea where it comes from or how to prevent it though.
First comes the message on the MM, shortly after the MM stops (faders still active), approx. 30 sek later the faders stop working, the the monitor section that's still controlling DADman stops working and finally the meters go down. So there's still some communication going on after the initial connection loss from the MM.
A few days ago it worked fine for like 3 hours, yesterday it happened every 2 minutes.
We do a lot of classical piano recordings so I doubt that PT has overload issues We run it on two HDX cards, IO is the AX32 with Penta pres.

If anyone has a hint how to solve this mess it would be a great save!

Thanks and best,
Julian

Everything that Eddie said.

If you have MTRX (AX32) + Dante on the same network as the EUCON surfaces I would separate them to a different network + NIC on the workstation.

Let us know.

Thank you very much, guys! So the only thing possible then that can help then is the port 2/1 switch and/or the update. We were a little hesitant to update because last time it got a lot worse, but I have faith now. We'll have that done and I'll get back to you if it worked.
Big ups for the quick help!

Best,
Julian

Oh by the way, we have the S6 on it's own physical network on EN0 of the MacPro and everything else like Dante, servers and internet on EN1. SO there shouldn't be any problems coming from here.

Hey guys,
so we finally found the time to update everything. Still didn't bring any improvement, so we thought that it had to be a hardware thing. Tried to narrow the problem and it seems to be the network switch or a connection to/from it (own dedicated switch just for the S6). We ran a loooong ethernet cable from the machine room directly to the S6 and tadaaa it worked. Gonna renew the cables and switch now.
So, still loads of thanks for all your help, maybe it will be a key to anyone having these issues in the future.
Big ups from Germany,
J
