Mosh crashed Aborting: _Unwind_RaiseException Mosh NaCl crashed.

I'm not sure if this is mosh-chrome issue, seems like might be actually server issue/crash?
But when PC wakes up from sleep, I find Mosh chrome with error inside saying:
Aborting: _Unwind_RaiseException Mosh NaCl crashed.
(Same happens if disconnecting from wifi and then reconnecting again.)

And when I login again I see a message:
Mosh: You have a detached Mosh session on this server (mosh [PID#HERE]).

I don't know if there are any logs anywhere.
I simply installed mosh 1.3.2 on server via apt-get install ...
Then I compiled/built (via ./build.sh dev) this mosh-chrome from git clone sources last night.
Appreciate any tips on finding logs on server and or how to diagnose or fix.
Long ago I recall using it and worked but wasn't using chrome extension client.

(I was trying again since on a 5G connection I was getting breaks that killed SSH too often, breaks that didn't really affect browsing or video streaming or anything else but apparently even tiny breaks can kill some SSH configs.)
