I have 2 easy reproducible cases:
- Reboot of Raspberry PI 4 with libreelec OS connected via 2.4 or 5GHz. It can’t access my server (connected to Omnia directly via ethernet) for the first ~250s, after that it works fine.
- Laptop reconnects from different AP (connected to Omnia via ethernet) to Omnia directly (I test with 5GHz only). The laptop can’t access the server for the first ~250s too, after that it works fine. Tested with Macbook Air and Lenovo with linux.
I also double checked: it’s not only my server can’t be access but anything connected to Omnia via ethernet. All the devices connected via WiFi are accessible.
I’d be happy to help debugging this, but until next week I do tests only with R-PI due to traveling.
