Homey Pro and Homey Bridge

I have a Homey Pro, connected over a wired connection and WiFi. I have a Homey Bridge on a different floor, connected over WiFi. They are both connected to the same SSID. At least once a day, the Bridge goes offline, displaying the red ring. How can I troubleshoot to identify what is going wrong? Worth mentioning the WiFi and Internet access are stable. No known issues.

Thanks in advance.

The bridge is very picky and can’t handle “modern” wifi very well.
