no response from server when using osrmTable()

[RWParsons]

When trying to replicate the calculation of a distance matrix using the example in the README, I get the following error message.

library(osrm)
library(sf)

pharmacy <- st_read(system.file("gpkg/apotheke.gpkg", package = "osrm"), 
                    quiet = TRUE)
travel_time <- osrmTable(loc = pharmacy)

Error: Error in curl::curl_fetch_memory(utils::URLencode(url), handle = req_handle) :
Empty reply from server

When running on a different computer, I get the following message:

Error: Error in curl::curl_fetch_memory(utils::URLencode(url), handle = req_handle) :
schannel: failed to receive handshake, SSL/TLS connection failed

When running on posit workbench, I get the following error message:

Error: Error in curl::curl_fetch_memory(utils::URLencode(url), handle = req_handle) :
OpenSSL SSL_connect: SSL_ERROR_SYSCALL in connection to routing.openstreetmap.de:443

but other times when I try (also on workbench) I get:

Error: OSRM API request failed [504]

Thanks!

Hello,
The OSRM demo server is not working properly, see Project-OSRM/osrm-backend#7037 (and this answer Project-OSRM/osrm-backend#7037 (comment)).
