1. Network connection problem: Please make sure your network connection is normal, and try to open other web pages or applications to check whether the network is unblocked.
2. WeChat version problem: Please make sure that the WeChat version you are using is the latest, and the old version may have some problems.
3. Maintenance or failure of official WeChat account: It is possible that Jinbin Veolia Water Industry Co., Ltd. is carrying out maintenance on official WeChat account or encounters technical failure. You can try to open it later.
4. Security issues: Sometimes, the official account of WeChat may be temporarily or permanently blocked by WeChat due to security issues, which makes it impossible to open it.
If the above methods can't solve the problem, I suggest you contact the customer service of Jinbin Veolia Water Industry Co., Ltd. or WeChat customer service for help.
