How can I troubleshoot a Viber error if I have a stable internet connection?

Even with a stable internet connection, try clearing Viber's cache and data (in your device settings). Reinstalling the Viber app can also resolve corrupted files. Restarting your device is another simple but effective step. Finally, check if Viber is experiencing widespread outages by searching online for 'Viber outage' or checking their official social media channels.
