Error problems, and server connection problems.

Every time I try to get on Gmod, when I click a server, every single one has the same, “Connection has failed after 4 retries”. I’ve worked my way around that by being invited or joining my friends, but when I’m in, All the counter-strike textures and meshes are gone and errors. I’ve verified all my Valve games that are installed thus far, and It’s still giving me the same problems. I’ve even re-installed them a few times also. I have no idea what to do.
