If your computer displays a protocol blocked error
message, several possibilities exist including the following three
common ones:
- intentional port blocking by an employer or parent,
- intentional port blocking by a Web browser
- port blocking by a
computer security program
For example, an employer or parent may be
concerned about the types of websites you are visiting or considering
visiting. Whether the employer doesn’t want employees going to job
hunting sites like Monster.com or a parent wants to ensure that children
don’t visit inappropriate sites, software and Internet settings exist
that will make the protocol blocked.
An employer may have the IT team
block specific ports, URLs, and protocols while a parent may use
parental control software to restrict access.
Web browsers also block
ports and protocols that have known vulnerabilities. For example, after
a cross-protocol attack in the early 2000s, Mozilla responded by
changing how protocols access certain ports. Port blocking by browsers
could generate protocol blocked messages.
Another common cause of
protocol blocked messages comes from computer security software that
recognizes a specific URL or protocol as being potentially malicious. In
most cases, if you encounter a message saying “protocol blocked,”
there’s likely a good reason.
