What should I do if my phone couldn't authenticate connection? (especially for Android)

Applicable to:
RoboVac 30C, RoboVac 25C, RoboVac 35C, RoboVac G10 Hybrid, RoboVac G30 Verge, RoboVac G30 Hybrid, RoboVac L70 Hybrid, RoboVac G20, RoboVac G20 Hybrid, RoboVac G35+, RoboVac G40 Hybrid+
During the process of connecting eufy RoboVac to WiFi, you might see the following error message: Your phone is not connected to the “eufy RoboVac 15C Max xxx” network. Please reconnect to eufy RoboVac 15C Max xxx in your phone WiFi list to continue setup. Please go to the Wi-Fi Settings and connect the RoboVac’s WiFi manually.
If you see the following message “Couldn’t authenticate connection” when connecting to it, please forget this network and reset RoboVac's WiFi. Then start the whole connection process again.
After you connect to the RoboVac’s WiFi successfully, you might receive a pop-up message “Internet may not be available”, please select "keep WLAN connection" and use the back button to go back to the eufy app instead of switching apps, because switching apps may cause the connection to fail.
