Dear all,

Hi. I've been trying to query gene name using biomaRt, but connection to ensemble site was failed as follows:

ensembl <- useEnsembl(biomart = "ENSEMBL_MART_FUNCGEN", 
+                       dataset = "hsapiens_regulatory_feature")

Ensembl site unresponsive, trying uswest mirror
Error in curl::curl_fetch_memory(url, handle = handle) : 
  Timeout was reached: [uswest.ensembl.org:8443] Connection timed out after 10002 milliseconds

Here is my session info: R version 4.0.5 (2021-03-31) biomaRt version: 2.46.3 Platform: Ubuntu20.04 on Windows 10 Pro Build21359.co_release.210409-1536 (WSL2)

I tried restarting but I still got the same error. Does anyone have the same problem? I will appreciate if you could help to solve the problem.

Thanks

Hi,

The Ensembl servers can become quite overloaded. Please re-try the command —possibly a few times, even more than 10— and it should eventually be able to create the connection object. I have just verified this.
