Yes, probably. There are also other issues. I will post the detail in repo issues later,
Discussion
I sent an EVENT message and everything seems to be working fine. How did you determine that there was no forwarding to the local nostr-relay-tray? The total number of events on the home page is dated. Because I cached the home page data 🌝
I use nak REQ to my local relay tray yesterday after sending event through hub relay. But, no worry, it seems yesterday I only have connection issue. It is ok, it works properly now 😅
There is another bug. Using v1.5.0 AppImage, with the following setting: Default block and only allow kind 1. But local relay tray reject all events including kind 1 that was supposed to be accepted.

I'll find the problem as soon as I can
Thanks Cody. It's ok, take your time.
I have fixed this issue in the latest code, but I plan to release it later. The "add hub" feature still has some unresolved issues, and I intend to release everything together once those are fixed.
