Hi, 

 

I have very frequent disconnects (I can reconnect immediately then). I read the user guide and I think I configured correctly.

I had suspected the reliability of the wifi connection but after connecting through ethernet traditionally (through the LAN's router), the occurence frequency is the same.

 

Can someone from HP take a look at these excerpt from the logs? I managed to isolate the events pertaining to the disconnect on both sender and receiver logs.

It would be much appreciated.

So, it's disappointing to trying to be supported by HP and ending writing all the posts ourselves.

After a lot of time lost I discovered these disconnects are caused by the macOS feature App Nap. When the activity diminishes, macOS removes resources/power/etc to Zcentral Receiver app to the point that the SyncPulse fails and the connection stops.

 

To prevent this, open Terminal and write: "defaults write [drop the HP Zcentral Remote Boost app from your Applications folder here] NSAppSleepDisabled -bool YES" > Then restart the receiver.

It might be related to this post: MacOS: ZCentral Receiver disconnects when switching from fullscreen app

@Tiltx (can you mention a user?)

 

My log is exactly the same as his, and it ends with:

Up until the moment it's disconnected

 

His OS was Mojave, I'm in Catalina

He was with 20.0, I'm with Receiver and Sender  20.1.1.8114

I'm also using fullscreen mode

 

I wouldn't phrase that it disconnects "when switching from full screen app", here it can disconnect after a long (random) period of time after I have switched from spaces and I'm working with another macOS app.

Hi, 

 

Maybe I should I have asked first. Are trial users entitled to support?

I'm surprised by the lack of response by HP employees 😞

Isn't this the appropriate channel? 

 

Thanks to give a quick look at my problem!

J

Hi Hoolito

 

I'm sorry you did not get any responses soon enough, but I'm glad you were able to find out the root cause of your issue.

We've been poking around the App nap feature but we were not able to reproduce any disconnects related to the app nap itself.

We still want to investigate this, though, so may I ask what sender OS and RB version you were connecting to?

 

Thank you.

Hi Lizzy,

 

I'm in Catalina.

Receiver (macOS)  20.1.1.8114 build Dec 18 2020

and Sender (Win10)   20.1.1.8114 (don't know how to check build)

 

FYI, after deactivating app nap, there were no weird disconnects

Hi Hoolito,

 

I just wanted to thank you for helping the community with the feedback on this.

The app nap issue has been fixed and will be available on the upcoming releases of Remote Boost.

 

Thank you.
