Note that when issuing HTTPS encrypted object storage, Huawei and Alibaba Cloud's HTTPS built-in authoritative certificate, iServer can be directly trusted without separate handling. However, for the HTTPS provided by the private cloud MinIO, it is necessary to make the iServer trust the relevant certificate in advance. Please refer to the configuration for specific operations of HTTPS-encrypted MinIO object storage .
