HTB Academy - Recursive Fuzz Issue

I have been stuck on this module since days. Issue is whenever i try fuzz command with medium list it takes a LONG time to scan for levels by the time I am on level 2 the IP expires as it has just 90 minutes validity. I have tried various changes such as using small list or common.txt but it produces no result. Below is the only command that comes close to working but IP expires by the time I reach level 2
