app works local, but unable to deploy - 'Error downloading package source: HTTP 599: Connection closed'

a MRE is provided below. This works locally, but when I publish I get 'Error downloading package source: HTTP 599: Connection closed'

#mafdb_hg19 <- MafDb.gnomAD.r2.1.hs37d5
#mafdb_hg38 <- MafH5.gnomAD.v3.1.2.GRCh38
#hg19 <- BSgenome.Hsapiens.UCSC.hg19
#hg38 <- BSgenome.Hsapiens.UCSC.hg38

ui <- fluidPage(
    # Application title
server <- function(input, output) {
# Run the application 
shinyApp(ui = ui, server = server)

The error I get when I try to publish Error: Unhandled Exception: Child Task 1167525167 failed: Error building image: Error fetching MafDb.gnomAD.r2.1.hs37d5 (3.10.0) source. Error downloading package source: HTTP 599: Connection closed

Since MafDb is large, I've tried the following in my Rconsole before publishing, but it did not help.


since GenomeInfoDb works, this tells me the repos for Bioconductor are set correctly,
