Using version 7.7.9, my IP always gets blocked after running for a while recently, and it's unblocked after a few hours. Do I need to update to a higher version to avoid this? The website is https://www.iwencai.com/unifiedwap/home. This situation occurred after the website updated to its latest interface a few days ago. Could it be that I've been identified as a bot?
