Changed wifi password all devices offline

Hi all,

I have a few shelly 2.5 roller shutter. They were working fine. Today I had to change wifi password because of legacy devices which have a limit of characters.

Changed pass, but then all shelly 2.5 devices appear offline.

Tried to setup batch wifi, it tells success but still not working.

Disabled 5ghz band and setup wifi again, not working.

Restarted equipments no result.

Remover one device to see if searching it would appear, nothing.

Going crazy on this thing what else can I do?

Just tried to put back previous wifi password and e everything works again.

Changed wifi pass again to new one, and boom everything stoped working again...

It is frustrating such an easy thing as changing a wifi password...

Yes that is what I ve done on my previous post (batch update shellys 1st, then update my wifi password), no sucess
