Dear,

I have been working on some software that uses the W3C CSS validator.

It has been working fine for a couple of hours but suddenly I can't seem to
connect with this service anymore through my software (I am using a Java
web service implementation).

Also I can not reach the https://jigsaw.w3.org/css-validator website via my
web browser. My internet connection is working fine however, I can access
any other website.

I'm thinking I my IP-address has been blocked or something, because I AM
able to use the validator via my phone's mobile internet (mobile provider).

Also, Windows Connection Troubleshooter reports:

'The remote computer isn=E2=80=99t responding to connections on port 443, p=
ossibly
due to firewall or security policy settings, or because it might be
temporarily unavailable. Windows couldn=E2=80=99t find any problems with th=
e
firewall on your computer.'

My 'blocked' external IP is 94.210.181.183.

Can you help me please?

Thank you in advance.

Cheers,
Axel Polet
