+            1. Ensure merchants API is running. If you are developing locally,
+            BitcartCC assumes it is running on port 8000 by default.<br />
+            2. Make sure <code>BITCART_ADMIN_API_URL</code> is set to the
+            correct URL.<br />
+            3. If you are using BitcartCC with ssl enabled, Merchants API's ssl
+            certificate might not have been generated yet. Please retry a bit
+            later.
