Although a connection was successfully made to the specified module repository. It appears that this repository is not yet sharing any modules
Last known problem like this was back in 2008? - is it my CMSMS or is it really down?

Yes. The code in the module manager page makes calls to external sites to display the list of modules and grab the code for the module you want to install. I can well believe some security products would find that behaviour suspicious enough to block. If you list what you installed someone cleverer than me might be able to help further.nikita9 wrote:Another thought i have had is i have just added several new security products to the server - could they be stopping the operation of the install?
