This sounds like a connection issue or a broken link.
You need to debug why these lines are failing:

	sudo wget --timeout=10 ${MAINLINE_URL}/${MAINLINE_BRANCH}${CURRENT}/${FETCH_FILE} > /dev/null 2>&1
	if [ ! -f "${FETCH_FILE}" ]; then
		DISPLAY_MESSAGE "${0}: Cannot fetch mainline kernel header file ... check your internet connection and try again."
		CLEAN_EXIT
	fi

Maybe run the script with -x flag, e.g. bash -x ./isorespin.sh.

I have exact same issue with version: 8.6.6. My Internet connection is stable though. I am on KDE Neon 5.20

Changing -u to -k v5.10.4 fixed the issue for me. I don't need 5.11-RC anyways
