Comet POE performance degradation on glkvm.com

I'm having trouble accessing my Comet PoE unit through glkvm.com. Often I get a 502 Bad Gateway error, and other times it connects fine, but after a while the connection becomes unusable, and everything runs very slowly. KVM is updated to the latest version.

We will release 1.9.0 recently, and it would fix or at least reduce such issue

I have upgraded to the 1.9.1 release and the issue persists.

Can you PM me the debug log?

Yes, I have sent some logs. Thanks.
