Message

Your PRODUCT version "VERSION" is too old. The minimum supported agent version for your account is "MINVERSION". Please update to a newer version with ngrok update, by downloading from https://download.ngrok.com, or by updating your SDK version. Paid accounts are currently excluded from minimum agent version requirements. To begin handling traffic immediately without updating your agent, upgrade to a paid plan: https://dashboard.ngrok.com/billing/subscription.
