[SOLVED] HELP! After update Hub UNREACHABLE

[WWJD]

After the last update, I could access the hub and browsed some options.
But then it became unresponsive so the only thing I could do was to do a power cycle.

Note:

LED is GREEN
last month I had to reset the hub every few day because it became unresponsive randomly (before the latest firmware update)
log says "LOW MEMORY" after the update, before it became unresponsive??
I have NO RULES, all rules are in Node-Red so not an overloaded hub
I have 30 devices

After that, I cannot reach the hub in any way, via it's IP address:8081 or via the app.

If I search for the hub via the app (settings>hub>select hub)

I see the hub, select it and then get this error:

ERROR
okhttp3
.ResponseBody$1@e961e8c

redone the power cyle several times and waited >10 minutes but to no avail.
any suggestions?

The scenario we hear about around here is that your IP address on the hub changed.

The Hub "phones home" after reboots and Hubitat will let you reconnect.

Thank you for your suggestion!!

The only thing I did not try was to leave the hub without power for 10 minutes.
That did the trick. IP address remained the same in my case

@WWJD

IP address remained the same in my case

You should have that as a reservation in your DHCP server...

Of-course, good point but that was the 1st step I did when installing the hub.

Maybe you did not read the thread: I was responding to comment of @csteele
