How do I regain access to my OpenBeken device after changing my router?

I have several devices on OpenBeken and I recently changed my router which changed my entire network configuration.
I have recovered all devices except one. I can see them by scanning the IP but when I want to log on there is a system info that the connection was rejected.
I also tried the power trick 5 times and it did not put up a hotspot.
Is there any other trick to get on it?
There is still the option of programming via cable but I would leave that as the last option. It is an aftermarket chip and I am in no hurry to remove it.

What exactly does system info mean? Show a screenshot. Is it about the HTTP level message or that you have enabled password authentication on the device?

This is the info from the browser after trying to connect after typing in the IP address. "This site is unreachable" and underneath "The server 192.168.xxx.xxx has rejected the connection". I have no connection to the webserver, i.e. I do not see any screen associated with it.

Since you changed the router, how does the device connect to the new one? Did you keep the password and SSID the same?

Switch the device off, wait a bit (to let the capacitors discharge) and switch it on again.

And does the Web App on it work? Try the address (change the IP to your own):
.

When I added the new router I managed to connect once and changed the login data to the new one, maybe I made a mistake there. the strange thing is that the iP scanner saw the device on the new address. Since then I have not been able to connect. app? also did not work.

What did work was that I waited for about 2 minutes after switching off and then powered on 5 times and it came up as an AP.
So I entered the data again and now I can see it and it works fine.
Thanks for your help.

So capacitors.... happens. It can be illusory. In any case, it's good that it works. If you have any other questions, set up a separate topic and you can send me a link on PW then I'll find it quicker.

Also, remember that we collect information about devices, here:
https://openbekeniot.github.io/webapp/devicesList.html
If you have something not on this list, you can also create a topic with a template and description of the device.
