I think I miss your attention
please sir, consider my application.

You used the Electrum signing format. Not compatible with OgNasty's software. Very usual mistake of Newbies - even some very smarter smartest Newbies make this mistake, I have seen.

Standardization of message signing for Segwit "bc1..." addresses is a work in progress.

Signmessage doesn't work with segwit addresses

Also, maybe instead of try three times the same thing, there may be better way... Like, give the message a massage, see if makes happy.
