Snipca not opening webpages.

Never heard of the program/site but that's not unusual, many sites on the Internet not really prominent/known about. A search finds more information, maybe one of the links on it works.
Snipca at DuckDuckGo

I’ve heard of snipca links from Computeractive magazine for their links, their suggestion is to enter the snipca like a normal link rather than searching for it.
Which snipca are you having problems with?

Hi,

Whatever snipca number is used I just get "Unable to connect" then "Firefox can't establish a connection to the server at snipca.com".

Please provide one of the snipca links so I can check it out.
Do you run any VPN or adblocking software?

The adblocker may be preventing the connection, have you tried disabling it then trying the link?

Hi
Just disabled Ublock and now all is OK.

Many thanks to all.

Good to hear.
