Sorry Your IP is Wrong(Toybox)

Sometimes when i start gmod everything is ok but when i go to the toybox tab it loads the first page but once i click on a tab it says Sorry Your Ip Is Wrong Are You Behind A Proxy?
After a few restarts it works fine but i have lots of addons that a restart will take a long time any one having the same problem?
Any Help would be appreciated.

I have the same problem after I changed IP Adress.
I can’t figure out what the problem is, I have been searching on Google for hours to find the answer for it, sadly, it never happened.

I found a fix yesterday for me first spawn a prop before you go into the toybox tab then you click on the favorites,mine,props,entities etc. it should work
**EDIT:**on your browser keep a tab open at this address
**EDIT Again:**Its confirmed that i need the toybox tab in my browser

Well, that is good news!
