r/razer on Reddit: Server Access Unavailable
February 13, 2018 -
Does anybody else have trouble installing Razer Synapse 3? Each time I try to install, I get prompted with "Server Access Unavailable". The only options I then have is to cancel the installation or retry. Retry doesn't work obviously.
It works just fine on my personal desktop, but cannot do anything on my laptop.
Any help is appreciated! Thanks!

Hi u/the_bacon8er , Please try the outlined steps below and get back to me via PM on how it goes: Close the application. Shut down your computer. Powercycle your ROUTER and MODEM. Once your network is back up, boot up your computer. Reinstall Synapse on your computer. Check if that'll make any difference. Best regards, Jace S. RΛZΞR | MarksmanMiya

Yes I have the same issue. Just keep clicking retry until it works, that solved it for me.
