D365 On Premise Communication Error

Posted on by Joe Spitler 2020

Hello Everyone

I have recently installed D365 v9.0.8 in a new multi-server environment. Two FE, two BE. The load balancer for the 2 FE's is being configured by my client. I do not have an update on that yet.

In the mean time I am importing organizations. The first one went fairly smooth, with a few glitches that I worked out. It's up and I can navigate to it just fine.

Two other orgs are not doing so good. They imported just fine with no errors in the log file. But when I navigate to them I get this:

"A communication error occurred while processing the async operation."

I cannot seem to find any information. I have restarted all services, even rebooted all servers, including the SQL Server. I am at a loss at the moment.

Any help will be appreciated.

Turn on tracing

Then look at the tracing logs. Those logs will tell you a lot more

Hello Joe,

Hope you are well.

Is this problem still occurring?

What extra details can you provide?

- Printscreens

- Small output of verbose logs exactly when you hit this error, enabling them with Crmdiagtool

Thank you.
