Hello everyone, I'm running a script to get informations about the genelenght using Biomart and is retuning with an error :(

mart = biomaRt::useMart("ENSEMBL_MART_ENSEMBL", dataset = dataset, 
                    host = paste0(ens_build, ".archive.ensembl.org"), path = "/biomart/martservice", archive = FALSE)

Error in curl::curl_fetch_memory(url, handle = handle) : Protocol "sep2015https" not supported or disabled in libcurl In addition: Warning message: Ensembl will soon enforce the use of https. Ensure the 'host' argument includes "https://"

I accept any advice to fix it

thank you

What is the value (or values) in ens_build? It looks like the host argument is being constructed incorrectly somewhere.

It might be easier to use the function useEnsembl() instead of useMart() and then use the version argument. e.g.

mart <- useEnsembl(biomart = "ENSEMBL_MART_ENSEMBL", dataset = dataset, version = 80)

I also don't think there is a "September 2015" archive, if that's what you're trying to access. Version 80 in my example is from May 2015, which is the closest I can see. You can see a complete list of archives with listEnsemblArchives().
