Squid Proxy cannot access website witch no default port

[Dacosta]

Dear all,
The Squid Proxy can only access websites with default ports 80 and 443. When connect the web with different port, it shows error:

ERROR
The requested URL could not be retrieved

The following error was encountered while trying to retrieve the URL: www.domain:8089

Access Denied.

Access control configuration prevents your request from being allowed at this time. Please contact your service provider if you feel this is incorrect.

Your cache administrator is admin@local.

Hi if is https://www.domain.com:8089 then you need to add 8089 to ACL SSL ports if not then in ACL SafePorts

If you setup squid/squidguard correctly, you don't need install certificate on the clients.

I watched this video and it helped me a lot:
