Dear all.

Using this library with dhcp and parameters for the MQTT everithing works well (code based on your AutoConnectWithFSParametersAndCustomIP).
when I try to use with fixed ip, just adding the line
wifiManager.setSTAStaticIPConfig(kIPAddress, kGateway, kSubnetMask);
After reboot it returns to AP mode again, it seems that the wi parameters are not saved.
Check bellow

_*WM: Configuring access point...
*WM: ESP1795988
*WM: AP IP address:
*WM: 192.168.4.1
*WM: HTTP server started

*WM: static netmask
*WM: 255.255.255.0
*WM: Sent wifi save page
*WM: Connecting to new AP
*WM: Connecting as wifi client...
*WM: Custom STA IP/GW/Subnet
*WM: 192.168.1.12
*WM: Already connected. Bailing out.

0000047.795: WiFi connected. IP address: 192.168.1.12_

->> It says already connected and gets the IP 192.168.1.12 but thats not true, pinging it, this ip doesn´t exist. After reboot goes back to AP mode

Thanks

Maybe try erasing flash, it might think its already connected and not apply the new ip

Dear @eXadra
Did you find the solution to the Static IP issue using Wifimanager?
I am still not able to set Static IP using the AutoConnectwithStaticIp.ino nor any luck with AutoConnectwithFSparametersandCustomIp.ino
On serial monitor it shows the IP which I have set, but I am unable to ping that IP.
AutoConnect.ino for dhcp works great. But i need static IP configuration which is not working

Thanks

And Do you have a working example for IP, subnet, DNS and hostname?

Not sure but the DEV/ example should have everything possible in it.
