There is a problem that we understand of, that somebody resolving the issue might discover their method to this subject, believing that Sefaira is down. So, I will inform you about it!
In Windows there is a network security setting, that has a low, medium, high settings. I’m relatively sure it defaults to medium, however if you have it set to high, and opened SketchUp that has the Sefaira extension, this dialog will appear every minute till you close it. If it’s been 20 minutes in between you opening SketchUp and you observing the dialog, there will be 20 of them accumulated.
The very same can occur on Mac, though I wasn’t able to set a difficult adequate security myself to activate it. But others have actually reported the issue, and resolved it once again by minimizing the security to a less severe level.
So, this dialog suggests your security is expensive, and not that Sefaira is down. It is obviously something that need to be enhanced! I have actually informed the best individuals about the concern.
