Dear All,
I have issues about Proxy Service not working on ProxySG S400-20.
My customer have changed configuration about Proxy service Explicit HTTP from Intercept to bypass for test something.
and after test completed they change config back to same before from bypass to Intercept.
after next day they found some client still cannot access to internet have error about proxy service please see picture as below.
I have seen this error before if client config Explicit HTTP and proxy service config to bypass will see error same above.
but my customer have config intercept explicit http port 80 and 8080 already please see picture as below.
some client still found error when access to internet but some client after refresh to recall website again can access.
but this issue we found many client in company.
i upload sysinfo of this appliance please see from attach file.
If have some information to recommend please help or have workaround please share.
Thank you for your help.
