BE30000 Troubleshooting Wireless connection issues & system log SSL entries

[RaidersHI_95]

I've been struggling with random disconnects on my main and IoT wireless networks with my BE30000 system configured in a router/double-NAT setup. My IoT device networks will randomly but frequently drop at various points throughout the day, and at least once or twice a day, my main network will lose connectivity for 5-10 minutes. Scanning the system log, I don't see anything very obvious, but I don't really know what I'm looking for either. I saw the other thread regarding turning off the 2.4Ghz on my main channel, but unfortunately, my Brother printer only supports 2.4 and I'm not sure if there's a way I can move the Brother to the IoT network while still being able to print to it from PCs on my main network?

The only log item that stands out is a repeating entries regarding the SSL certificate?

Apr 8 21:29:43 httpd: Failed to initialize SSL, generating new key/cert...8443
Apr 8 21:29:43 httpd: Unable to start in SSL mode, exiting! 8443

The above 12 lines repeat over and over again continuously. Is this somehow related to my wireless connectivity issue?

Any insights or help is greatly appreciated! Asus support is less than communicative and helpful.

I forgot to mention, I'm running it in MLO wireless backhaul, with two nodes connected to the main router, which is behind my provider's gateway router. All three units are running firmware version 3.0.0.6.102_36909.

I noticed the following entries in the log at the same time I recall the network dropped:
