Running two umbrels on same LAN, seeing slow/no replies. HELP

General Discussion
1

Both servers are consistently very slow to reply to HTTP. I suspect some type of collision/conflct around the two hostnames (e.g. Both may be competing for umbrel.local).

I’ve assigned:
Different local hostnames via Settings > Advanced > Network > Hostname
Different static IPv4 addresses (via my OPNsense router)

I tried rebooting each, several minutes apart from each other.
Both show their unique local hostnames (at Settings > Advanced > Network > Hostname)
Still seeing what feels like a hostname (or arp) collision.
No similar issues with my start9 in same topology.

How best to resolve and run?
Happy to share umbrelOS logs, if needed.

Thanks, in advance, for any pointers!

You have to rename host and fix the IP on DHCP server.

Connect to each of them via browser using their IP addresses instead of hostnames. Also try ipconfig /flushdns if running a Microslop OS.
