Need help with understanding why my ESP32 is disconnecting from caster

[mbackonja]

I often have disconnections between esp32 and the caster. These are in random intervals between 5 minutes and 20 minutes. In periods when there are no interruptions, the connection lasts for 7+ hours (a couple of days a week), while most days I have 30+ interruptions every 5-20 minutes...

WiFi is not a problem, I changed 2 3G routers, 1 4G router, and home WiFi... My RTK Base is right next to the router... My ESP32 is on the UPS, I restarted it today, but it had 27 days of uptime previously...

Nothing helps...

I tried both the stable version 0.5.2 and the latest version 0.5.4...

When I open log.html, this is what I see:

And I can't understand what's the reason for those disconnections...

@nebkat can you help me understand what's causing it?

P.S. This message

I never saw it on 0.5.2 version, this is the first time I see it now (on 0.5.4 version)
