Lost wifi connection, app offline

[timinwinchester]

I had my system installed last week, and it was working Ok, I think. And then,
This afternoon, my mobile app went offline.
The wifi dongle module on the bottom of the inverter is flashing red quickly, showing no wifi connection.
I've looked around on this site and followed the advice to try resetting the entire system (powered down the inverter, and battery, and then powered it up again). That didn't work.
I tried unscrewing, removing and then replacing the wifi module dongle. Still not working, still the same rapid flashing light.
I followed the advice in this helpful image

to connect to the wifi module on my phone; for me, this is W-497A119, which is already stored in my phone's system, with the password mtmt2020 coded in. When I am connected to that network, I then went to 192.168.1.1 on a separate browser and hit enter
Here's where I get something different from what I expect. I get a page asking me to log in to the admin account (which can't be changed, there's no way I can try to log into a different one). If I enter my wifi network password, it gets rejected (abnormal login, as shown in the image below) as does mtmt2020. So I can't get past this to the page where I can select my home network and then put that network password in
Can anyone help me work out how to get my app reconnected, please

Hello,

That model wifi module needs you to use the fox 2 app to setup not direct over the wifi like how you're trying.

Ha! Will, you're a star, thank you. I spent ages on this trying to do it manually!
For anyone who has a similar problem to me in the future, Will was right!
I went into the app.
Used the "me" button at the bottom left and selected WLAN configuration

let it search for devices, and it found my module (shown in the middle of this picture), so I selected that, connected network and entered my wifi router password, and we're back on again.

Really appreciate your help, Will.
