Dynamo crashes when loading

When I try to open Dynamo in Revit it gray out in main menu, I’m using Revit 2018.3 and now I reinstalled dynamo to 2.0.3 version. In log files I have found this:

2020-05-01 12:54:56Z : ERR_CONNECTION_REFUSED

Does anyone know how to solve this?

I looked through old log files and I found that probably Dynamo wants to check if there is new version available. So I checked my firewall but it was not a problem.

Can you provide a screencast showing what is happening?

Not anymore, yesterday everything started working normally. I guess it was some kind of network issue, sorry that I was bothering you.

Not a bother at all! Those networking issues can be a real pain to troubleshoot and resolve. I’m glad you are back up and running. :slight_smile:
