the reason is that there is a problem with the page certificate ~

you can check
1 to see if your phone has ever installed software such as a proxy, which may install a self-signed certificate on the machine, which may not be trusted, such as fiddler's certificate.
2. If it is not installed, check the network environment to see if this will happen when switching from wifi to 4G.
3. If not, try another phone, connect to the same network as you, and see if this happens
4. Check the certificate signature of the website

.

if it is a website configured with https, it is generally due to the lack of intermediate certificates.
generally speaking, the purchase certificate will be given to the intermediate certificate. If not, it can be generated based on the existing certificate.
intermediate certificate generation address: https://www.myssl.cn/tools/do.


is the certificate configured correctly? check it.
