Proxies don't work on browser (no connection)

I get error when i try to access internet through my proxies. Tried mozzilla and chrome. No luck.. worked before. Proxy admin panel says the ip's are all online and my accounts are running smooth on FL. I need to login to IG and verify account. Tried everything. Anyone knows what might be problem?

You might try adding proxies in some proxy toogle software instead of browser. you can try them in scrapebox or another proxy checker or just change them in your provider if that's possible.
