enrichkegg函数报错

[PanSX-Dr]

于老师，我最近在用clusterprofiler进行kegg分析，运行enrichkegg函数的时候代码如下：kk <- enrichKEGG(gene = gene, organism = 'hsa', pvalueCutoff = 0.05)，但是提示报错信息如下：Reading KEGG annotation online: "https://rest.kegg.jp/link/hsa/pathway"... Error in file(con, "r") : cannot open the connection to 'https://rest.kegg.jp/link/hsa/pathway' 此外: Warning message: In file(con, "r") : URL 'https://rest.kegg.jp/link/hsa/pathway': status was 'SSL connect error'。尝试过很多问题，请问这个该怎么结局。
