mullvad-find-valid.sh

# This script iterates through Mullvad's servers in order to find a valid (non-geoblocked) IP for HBO Max

mullvad relay update && mullvad connect

# Replace "us" below with the country code you desire
for i in $(mullvad relay list | grep -ow $'\t''us\S*'); do
	mullvad relay set hostname $i
	sleep 3
  
 	# Copy your full request to HBO's (or similar service) session URL including your cookies and user agent
	curl -H "https://oauth-us.api.hbo.com/auth/tokens" [...] | grep geo_blocked
