KMD Reward claims

[TonyAV82]

Hello there, I have exercised couple times already hard time claiming my KMD rewards, I have my KMD on my ledger nano X and usually I used to use this website https://dexstats.info/rewards.php?address=RF4jGWEheWmhsxBpjbqB81pYjc6jw7gTFq then last couple of months I had an issue with it and I have switched into Magnum wallet now they are temporarily suspended, I found this website https://atomiclabs.github.io/ledger-kmd-reward-claim/ and now when I connect my ledger device and open my KMD app on it and press "check rewards" I approve the path then approve the address then export the first public key after that
"Connect and unlock your Ledger, then open the Komodo app on your device." shows checked (green checked mark on right side) but after that there are some other keys also should ask me to export to be able in this step "Approve all public key export requests on your device. There will be multiple requests" but it doesn't and after a while it gives error "Failed to fetch" and my ledger device and KMD app on it all up to date
Thank you for your help , my rewords stopped because it passed 30 days and it doesn't accumulate before I withdraw my rewards.
Please help me to fix this issue
Thank you in advance
Sincerely
Tony
