1. Reopen WeChat and enter the official account of China Resources Gas WeChat to see if this message still appears. If it is a temporary network problem, it may recover automatically.

2. Please check whether your network connection is normal and make sure that the time and time zone of your mobile phone are set correctly.

3. Try to clear the cache and data in WeChat, and then reopen the official accounts of WeChat and China Resources Gas WeChat.
