It has come to our attention from multiple clients that there is a bug in the OVH.com server providers firewall that prevents access to some of our servers. This causes accessibility issues when trying to install or upgrade scripts, e.g. csf.
If you have a server at OVH.com with this issue and use their external firewall offering, then you need to either turn off their firewall for the server or, if possible, whitelist the IP addresses for:
download.configserver.com (currently 85.10.199.177) – for all our scripts
license.configserver.com (currently 85.13.213.202) – for cxs and msfe
Lastly, we would suggest you report the issue to OVH.com and hopefully they will fix their firewall product despite their protestations that they are not blocking anything.
