Unable to log in Fing Desktop v2.0.0 app when fixed IP address is assigned to laptop

Hi I'm using Dell laptop running windows 10 pro 2004. Recently I tried Fing Desktop. After many attempts, I was unable to login the app from my home network through Wi-Fi, though net was working fine. After entering login credentials in browser, the app opened but I couldn't sign in. When I connected to a new Wi-Fi network (at home itself using mobile hotspot), I could log in easily. Then I connected to my previous home Wi-Fi network. Since I had already logged in now, the app was working but showed that I had  lost connectivity though net was working fine. I have given a fixed IP address to my laptop and incidentally, when I changed the setting to DHCP the previous network also was detected. So, as of now I have realized that fing desktop app only works if DHCP is enabled for the Wi-Fi network that's connected and doesn't detect the network if a fixed IP address and DNS is assigned to the WI-Fi from windows network settings. That's why I could login using mobile hotspot as it was DHCP.
This issue is not there in Fing app in my iPhone which also has a fixed IP and DNS address. Hope there's a solution to this issue or maybe an update resolves this issue.
Thanks

    Although you provide a very confusing question, I believe the answer is relatively simple and often overlooked. When using Dynamic Host Control Protocol, your DNS is also assigned automatically and is usually the same as the "gateway" IP of the router. Even if the Static IP assigned to the devices fits the current network IP scheme, the DNS also has to be assigned manually. Whenever certain cloud functionality is necessary on my clients' networks, I will assign the ISP's primary and secondary DNS server addresses. What you explained sounds to me like you are experiencing a "DNS conflict" and not an "IP conflict". Both have to be rationalized. Occasionally, you can enter the local DNS (same as the gateway) as the primary and use the carrier's primary DNS as the machine's secondary. This might make Fing work for you consistently. It's a little tricky mixing up DNS servers on a local network when you have a combo of Static and Dynamic addressing. I've achieved best results when I program statics on all of the hardwired ethernet devices (PCs, printers, scanners, etc.) with the carrier's primary and secondary DNS addresses, but allowing the wifi devices to DHCP (these will automatically obtain the proper DNS).

    I believe Fing actually did it's job here and isn't responding consistently because of a DNS conflict and the "log in" just doesn't know where to go. I could be wrong, but this is what it looks like to me. Good luck..

    Thanks for the reply Commgeek12, but this is not the issue as I've already assigned fixed DNS address (same as gateway) to my laptop on home Wi- Fi without any success. I even tried using public DNS addresses like 8.8.8.8 but that also didn't work.

    After entering the login details correctly, I'm redirected again to the sign in screen on Fing app if DHCP is not enabled.

    Once I'm able to login after changing the connection to DHCP, if again I give a fixed IP and DNS address to my laptop, fing app shows as  disconnected but i'm actually connected and net is working fine as shown in the screenshot above.
