Proxy requires password and user name

Running High Sierra.

I started getting this message when I first open chrome:

the proxy http://11.adams-aqua.ga/ requires user name and password

A couple of weeks ago I stopped being able to browse with any browser because some problem with the proxies. Searching the internet I found as a solution to just disable all proxy settings.

I found this solution rather lame, but it worked. Also I read that it was better to have use some proxy as it would take less time to request pages from servers.

I would like to just have whatever is normal as proxy settings but failed to find a tutorial explaining this.

Thanks!
