No response after "Wallbox is processing pwnware..."

[SenorSmartyPants]

I've tried this several times, factory reset the WB and with the laptop right next to the WB. This is what usually happens.

WB firmware 5.1.4

WB is detected
bluetooth chip BGX
connect to WB AP
pwnware sent
processing... and then hangs there forever
WB AP disconnects from the laptop almost immediately though

I'm not sure if it is actually pwnd since the final message never comes up. But I do try to ssh to WB and I get
[email protected]: Permission denied (publickey).

Would I get this error if it is not rooted?

Am I possibly correctly rooted, but just having ssh problems?

Here is a verbose output of my ssh connection attempt. (run from windows, I can provide linux version too)

Did you find a solution to that? My situation is similar except my process aborts even after "Sending pwnware"

Restarting the wallbox helped me to get the pwn work
