HTTP 403 Forbidden when trying to download available record

未指定 repository 文件或测试。首先使用 AnnotationHub 重现 R 示例，并检查对 https://annotationhub.bioconductor.org/fetch/126071 的失败请求，包括确认 Ensembl API 的变更是否会影响该请求。完成的标准是 AH119325 资源能够成功下载，或将问题缩小到外部服务变更，并记录相应的 workaround。

Hello, I have been running the following code over the past few months and now errors. Steps to reproduce included.

Not sure where it may be going wrong, maybe it's due to the ongoing changes to the Ensembl API?

library(ensembldb)
library(AnnotationHub)

# Get db cache
ah <- AnnotationHub(cache = ".cache")

# Query for human EnsDb object
ens_query <- query(ah, c("Ensembl", "113", "homo sapiens"))
ens_query
